Whilst most celebs have been sunning themselves in St. Barts or skiing in Aspen, Leighton Meester has been working to get “singing career” off the ground.

At the opening party of Miami’s newest nightclub Klutch, the actress/”singer” wore a sexy Christopher Kane Spring 2009 LBD with the trademark scalloped edges which featured heavily in Kane’s Spring 2009 collection.

It’s been hard to maintain a style crush on Leighton Meester recently, as both her looks and make-up have been very questionable.

But here she gets back on track looking sexy, chic and confident pairing her dress with YSL suede ankle boots.

I love everything about this look which grants her the first place in the BDOTW poll.

Leighton Meester hosted a post-New Year’s party at the Venetian in Las Vegas on Saturday night and again she didn’t let us down in the style stakes.

She looked fresh faced wearing a Nina Ricci Resort 2009 layered spaghetti strapped dress with a ruffled asymmetrical skirt.

Her dress was paired with Derek Lam Spring 2010 strappy sandals.

I’ll do my best to pretend that her good run wasn’t spoilt by this lace and taupe pant ensemble at Dusk night club on NYE in Atlantic City.

I could’ve loved it, if it weren’t for those pants.
