Katy Perry and Rihanna are good friends so when they realise they wore the same knitted H&M sweater dress a day apart, I’m sure they will have a good laugh about - especially as neither appear to be wearing make-up.

Katy Perry was spotted leaving Philippe Chow restaurant in LA this week, wearing her belted sweater dress with black knee-high boots.

The make-up free singer still manages to look gorgeous as she heads to her car.

Rihanna appeared to be a a foul mood when she left her Nobu in London last night.

What’s up RiRi? Did someone diss your fanny pack?

It maybe a Louis Vuitton fanny pack, but it’s still a fanny pack.

The singer who performed at the Brixton Academy this week wore her dress with workman type boots, sunglasses and a long gold chain.

I just can’t get over the fanny pack, so Katy wins this for me.

As much as I hate to admit, it looks like Katy, Rihanna and I share the same taste in fashion as I have this same dress in my closet.

I think I might wear it today - without a fanny pack.

We may have thought Hayden Panettiere, Olivia Wilde and co. were the first ones to wear the Jimmy Choo for H&M collection, but it appears that the claim to being first is actually held by Demi Moore.

On the 19 October the actress wore a suede grey one-shoulder Jimmy Choo for H&M dress to the “Laura Day Book Launch Party”.

She accented her dress with a black waist belt, and paired her look with snake skin heels and a black clutch complete the look.

So if you think this collection is just for teens, think again.

As if I need to remind you, the new collection hits stores on 14 November.

11 days and counting until the H&M for Jimmy Choo collection hits stores, but the stars were out to celebrate the collection in LA last night.

Hayden Panettiere probably had my favourite head-to-toe look pairing a Jimmy Choo for H&M sequined zipped black cardigan, with leather pants and a zebra printed bag with studded details from the same collection.

Olivia Wilde wore a black long sleeved Jimmy Choo for H&M dress which is covered in rhinestones.

She picked a perfect pair of heels from the same collection which were also embellished, but it’s her croc Jimmy Choo for H&M clutch I’m lusting over.

I almost cried when I saw Garcelle Beauvais on this red carpet, because I have been cruising H&M Regents Street, Oxford Circus and Brent Cross looking for this Holiday 2009 black long sleeved dress for a while to no avail.

It looks stunning on Garcelle as she paired her dress with a pair of strappy high heels.

I wonder how Tamara Mellon felt when she saw Paris Hilton arrive wearing Louboutin’s.

Paris did look hot pairing the black Jimmy Choo for H&M jumpsuit with a hot pink clutch from the came collection.

The Jimmy Choo Kase oval clutch is still a celebrity favourite on the red carpet.

I can’t believe the jumpsuit is only £39.99.  It’s just be added to my wish list.

Sister Nicky Hilton opted for a batwing sleeved Jimmy Choo for H&M beaded dress which shimmered on the red carpet.

Pairing her dress with silver strappy sandals, Nicky also carried the same starred croc clutch as Olivia.

The ankle boot trend was alive on this red carpet as Rashida Jones paired her Jimmy Choo for H&M grey open-toe and studded heels, with a black dress and a biker jacket.

She also fell in love with Hayden’s zebra print clutch.

Maggie Grace was just that….graceful on this red carpet.

Her ivory dress was accented with black accessories including black patent Jimmy Choo for H&M strappy heels which are number one on my wish list.

M.I.A. can usually be too crazy for my tastes, but on this occasion I love what she is wearing.

She paired Jean-Charles de Castelbajac Spring 2010 blue chiffon blouse embellished in sequins with a shark print motif, with black leggings.

Thigh high Jimmy Choo for H&M boots complete the look.

Ginnifer Goodwin was one of the first celebrities along with Nicky Hilton and Katy Perry to get her hands on the Matthew Williamson for H&M collection.

She wore this multi-colour sequined dress when she hosted an evening at “Prive Las Vegas” inside “Planet Hollywood Resort & Casino”.

At the launch of the “Matthew Williamson for H&M collection” aboard The Majesty in New York, Matthew Williamson and model Daria Werbowy posed together on the red carpet.

She wore the same dress as Ginnifer, but she belted her dress and wore booties.

The dress looks so much better worn without a belt, so Ginnifer wins for me.

Tyra Banks toned down from last years event where she was easily one of the worst dress, to one of the Best Dressed of this event - which wasn’t that much of a challenge.

The TV presenter arrived on the red carpet wearing a coral one-shoulder Rachel Roy Resort 2010 dress, with beige Manolo Blahnik heels and a Sang A nude clutch.

I’m loving the natural look she’s giving us these days, it’s so refreshing and it totally suits her.

She was able strike the right balance of elegance & sophistication.

Ashley Jones wore a flowing backless Matthew Williamson for H&M Summer 2009 floral gown.

Some of you may have this dress in your closets if you were lucky enough to buy this gown before it sold out.

I love the tiered ruffled skirt and the neutral accessories she paired with her gown.

Portia de Rossi’s navy off-the-shoulder Monique Lhullier Resort 2010 gown is absolutely stunning in its simplicity.

My only disappointment is that opted for thong sandals to complete her Grecian look.

She’s married to Ellen DeGeneres not Tom Cruise, surely Ellen wouldn’t object to her wearing heels.

I much prefer Heather Tom’s choice of this navy Zac Posen Pre-Fall 2009 fringed dress, as I feel the burnt orange colour wouldn’t have been flattering to her colouring.

The dress is exquisite which she pairs with Christian Dior heels.

Lara Spencer wore a black and white asymmetrical ruffled gown accented with a red belt.

Her gown was a bold choice and will no doubt have you on the fence, but I was crushing on her Valentino Couture red patent bow peep-toes which was on my favourites list last week.

Lori Loughlin elegantly posed on the red carpet wearing a peachy satin asymmetrical Enzoani gown with embellished details on the shoulder and hip.

Gold tone accessories including Loree Rodkin jewels, Renee Caovilla heels, and Bottega Venetta purse completed her look.

Jennie Garth channeled old Hollywood with her wavy ‘do and vibrant orange Issa gown accented with a sparkling brooch.

She sparkled with silver accessories.

Kirsten Storms sported a wavy ‘do as she walked the red carpet wearing a Tadashi Shoji navy silk chiffon one shoulder gown with white silk organza rosette strap.

Her look was paired with a navy Kotur clutch.

Rachael Ray was one of the winners of the night.

She walked the red carpet wearing a plum draped halter dress with a gold coil neckline.  She was one of the few to opt out of wearing a gown.

Susan Lucci is very much the Queen of daytime soaps.

The Queen shone brightly as she sparkled in a coral embellished halter neck Zuhair Murad gown.

Gina Tognoni looked sensational in this raspberry bow tied gown with a ruffled cascading down the front of her gown.

Like the dress, but I’m not crazy the hair.

Marcy Rylan opted for the mothers-to-be favourite red carpet Peas In A Pod gown.

This rose gown with a rosette detail on the shoulder, was also worn by Kimora Lee Simmons.

Kristen Alfonso attracted me with her stunning electric blue one-shouldered gown.

The embellished neckline is also exquisite.

Nadia Bjorlin was oozing sexy glamour wearing a backless gown, with a gold embellished detail draping from her neck and down her back.

Taylor Spreitler’s fuschia pink one-shouldered gown was one of my favourites.

It’s’ simple, colourful and she didn’t over accessorize her look.

Michelle Stafford strapless floral black and white gown is beautiful.

I love any dress that give a woman this stunning Jessica Rabbit/mermaid silhouette.

Stacy Haiduk was the joker of the night as she carried a cat purse on the red carpet.

Kourtney Kardashian joined her sisters at the Clevelander Hotel for a party to celebrate the grand opening of their “Dash Miami” store.

The reality TV star wore a printed Matthew Williamson for H&M maxi dress, which she accessorized with a black clutch.

Estelle wore the same dress when she attended a H&M event to unveil “The Fashion Against AIDS Collection ” in New York a week later.

The singer dressed down her maxi by pairing it with a denim jacket.

Orange pumps and a black Chanel quilted bag completed the look.

Neither have the height to pull this dress off, but I prefer Kourtney’s dressed up look to Estelle’s dressed down look, so Kourtney wins for me.

Katy Perry loves high street clothes. We’ve seen her many times wearing Topshop and H&M often mixed with more expensive pieces.

She was one of the first celebrities to wear a stunning peacock dress from the Spring 2009 Matthew Williamson for H&M collection, when she attended Paper magazine’s “The Beautiful People” party in New York. This was not the only piece she purchased from this collection.

Since then she has been spotted wearing the olive cropped leather jacket, and this week she was spotted in London wearing an olive satin jumpsuit with a drawstring waist and embroidered details from the same collection.

She follows Nicky Hilton who has also been seen wearing many pieces from this collection.
