Rachel Bilson has an accessory-obsession.

In July it was the green Chanel Wayfarers.

In August it was the hunter green shoulder bag.

Recently Rachel has been unable to leave home without her newest obsession - her 3.1 Phillip Lim ‘Edie’ bow studded bag.

We’ve seen Rachel strutting about town getting a good wear out of her new love.

The ex O.C-star carries her ‘Edie’ everywhere; to grab a coffee, shop at Staples in LA, stop off at her local Gelson’s and it’s still by her side on her way to an audition.

Also loving the Edie is Diane Kruger, Nicky Hilton and Leighton Meester, notice Leighton’s brightened red and navy version.

A warm alternative and perfect Christmas-present colour! Get hinting ladies….

We’ve only found this bag online at Colette and we’re just as in love with it as Rachel.

We all know Kate Moss loves YSL bags, from the Downtown tote to the Muse bag.

She’s fronted many campaigns for YSL, but think her love goes deeper than being affiliated with the brand as she recently added a new bag to her collection - Yves Saint Laurent Le Sixième printed stingray bag.

Kate was in spotted in Paris recently looking effortlessly gorgeous wearing jeans and a blush shirt, as she and boyfriend Jamie Hince shopped at Prada before returning to the Ritz Hotel.

It was at this point we got to see her stunning new YSL bag.

Kate is the first celebrity to be seen with the YSL Le Sixième printed stingray bag, and I’m sure many others will follow.

The bag is currently begin sold exclusively via Net-A-Porter.com and YSL boutiques for £1,145/€1,395.

Tinsley Mortimer was on the same flight as me from New York to London, and I guessed I would see her around London for Fashion Week.

After the Graeme Black Spring 2009 presentation I spoke to Tinsley Mortimer about her YSL Folies heels which she loves so much.

She told me that it hadn’t dawned on her that she wore her YSL heels so often.

Having brought them 2 seasons ago, she had forgotten all about them in her no doubt huge closet.

Upon rediscovering she now loves them so much she can’t bare to be parted from them.

Her stay in London is very brief, but she told me that she will also be attending the Luella and Issa Spring 2010 shows.

She will be skipping Milan, but will be back in Europe for the Paris shows. No doubt front row at Dior.

With her Folies heels she wore a Graeme Black Fall 2009 dress paired with a black belt and a fringed clutch.

Tinsley was busy on her blackberry when another guest took her front row seat wearing the same dress. Oh my.

This seems to be a new trend. First Pink and Sharika and then Blake Lively and Georgina Chapman.

Thanks again to OOooOO I Want One Of Those for taking the picture of me and Tinsley.

It seems Rachel Bilson loves green.

Firstly she fell hard for her green Chanel Wayfarers, and now she has fallen for her cute hunter green shoulder bag.

It would be safe to assume the bag is by Chanel because of the chain handle, but Topshop bags have this same chain on their bags and I can’t see any logo to confirm.

My guess is that it’s a vintage bag, due to the classic structured shape and top handle.

The bags envelope-like flap is accented with gold plaque.

Rachel has used this bag to collect her dry-cleaning, shop, walk her dog and enjoy nights out with friends.

It seems she just can’t leave home without it, and who can blame her it’s gorgeous.

Sienna Miller is currently in New York as she’s rehearsing for her Broadway play “After Miss Julie”.

Her morning starts the same everyday:

- rose tinted glasses
- starbucks
- comfortable flats
- cute outfit
- Prada Saffiano & Tessuto Tote

Sienna has been rehearsing for 3 days, but she can’t bare to be parted from her Prada Saffiano & Tessuto Tote.

The tote has a classic Dr. Watson feel about it.

It’s the kind of bag you carry and it instantly makes you appear smarter, like glasses.

Yesterday Flora said that she admires both Diane Kruger’s and Rachel Bilson’s style off the red carpet. I would second that and also add Sienna.

We’ve 3 great looks here from a simple grey tank and jeans, to a nautical stripe tank with a Twenty8Twelve skirt with Rupert Sanderson brogues, and a sweet floral Topshop dress with black ballet flats.

Effortless, chic and cute.

The deep burgundy saffiano leather tote with nylon insets, has double briefcase handles with square rings and a detachable shoulder strap with gold hardware thorough-out.

You can purchase this tote from Saks.com for $1,550 or Prada boutiques worldwide.

Elle Macpherson appears to be an unofficial brand ambassador for Victoria Beckham’s dress collection, because yet again the supermodel was spotted on “The Beautiful Life” wearing a dress from VB’s Spring 2009 collection.

The obsession started back in May this year when Elle wore a strapless black Spring 2009 dress to “The CW Network 2009 Upfront” event in New York.

She was no doubt drawn to the sleek structured design that enhanced and flattered her toned body.

All the pictures we have seen of Elle on set of “The Beautiful Life” this month have all been in VB’s Spring 2009 and Fall 2009 designs.

In the show Elle is Claudia Foster, a former Eighties supermodel who runs a modelling agency. Which explains the big hair and the pout.

In the most recent picture she looks like school teacher which is quite confusing.

Katherine Heigl doesn’t leave her house without her Spring 2009 ‘Marc Jacobs Memphis Python Robert Lexie’ tote.

The eye catching bag is perfect for summer with it’s bright yellow python leather.

The stand-out drawstring tote has a metallic burgundy and black circle motif with metallic nylon straps.

Its large 16″x 18″ dimensions allows this tote to be perfect to carry to the office, shopping trips or use as overnight luggage.

I love the colorful tassel and contrasting colours.

From meetings to an airport check in, Katherine carries her tote everywhere including…

…the “Letterman” show, where an assistant held her bag whilst she posed for photographers. Katherine can’t be away from her baby for too long, which makes sense when you check out the price.

You can share Katherine’s obsession by purchasing this bag from Barney’s for $4,200, or you can purchase a smaller version from Saks.com for $1,995.
