Kelly Rowland WOWS In Embellished LBD For Dinner With Simon Cowell In LA

Kelly Rowland was obviously dressed to impress on Tuesday night because THAT's what we call an LBD.

The former Destiny's Child slipped into her form-fitting embellished frock as she joined fellow judges Simon Cowell, Paulina Rubio and Demi Lovato at an X Factor finalist celebration at SLS Hotel.

The sexy dress featured a low-cut back, and she finished the look with an intricate chignon and sky-high heels.

Kelly recently joined season three of the US version of the show, and the top 12 contestants will now battle it out for the prize, starting 6 November.

Rowland has now worked as a judge on both shows, and recently said the US version is more rehearsed than the UK's, which she judged back in 2011.

And she's certainly stepping up to the style plate, too.
