Kelly Rowland is one star who isn't afraid to experiment with bold and bright eye makeup, and her look at The X Factor press launch in London on Wednesday was no exception.

Clad in a sexy, form-fitting black Versace number, the R&B singer sported emerald eyeliner that matched the eye-popping green panel on her dress. Careful not to look overdone, Rowland, 30, lined just her bottom lash lines with the bright hue and opted for a soft, shimmery lavender shadow on her top lids.

Lately, the "Motivation" singer has become a pro at using her eye makeup to add a pop of color to her ensemble: for her album launch party on July 26, Rowland, clad in an all-black Cushnie et Ochs dress, lined her bottom lids with an electric blue eyeliner.

And at a Sean John fragrance preview on August 3, she coordinated the color of her dress with her shadow choice, donning violet-rimmed eyes with a purple frock.
