Last night in Las Vegas Celine Dion performed on the first night of her new show at The Colosseum at Caesars Palace.

The singer who ended a five-year run at The Colosseum back in December of 2007, is beginning a three-year residency at the 4,300-seat venue.

She kicked off her first night wearing some stunning Couture and ready-to-wear looks.

Her Elie Saab Spring 2010 Couture strapless gown is heavenly.

The sexy gown with a lace lined thigh-high split has been modified to include embellished details on the bodice to make it the perfect performance look for a diva.

Celine’s other Couture look was an Armani Privé custom gown which closely resembles the Spring 2009 runway gown which was worn by Anne Hathaway during the 2009 Oscars.

Apart from the difference on the bodice, the directions of the paillettes on her gown are vertical whereas they are asymmetrical on the original version.

When I first started my blog 4 years ago, Celine was one of the only celebrities wearing Balmain.

After giving birth to twins 5 months ago she still has the perfect body to rock this gold Spring 2010 Balmain gold sequin mini dress.

I love the fringed details which will provide her with plenty of movement on stage.

Celine’s other Balmain look was a black sequined plunging gown with a thigh-high split.

Kate Beckinsale wore this same gown to the 2010 Cannes Film Festival ‘Biutiful’ premiere.

Kate opted for a wide belt, which gives the look some shape and prevents it from feeling so heavy.

Giuseppe Zanotti heels completed this look.

The Elie Saab gown is my favourite.
