It's Nicole Scherzinger from the Pussycat Dolls! This photograph was taken during a 2011 press conference in Los Angeles promoting FOX’s The X-Factor. In June of 2011, Scherzinger joined the panel of judges alongside Simon Cowell, Paula Abdul, and LA Reid.

Probably her largest success is as the lead vocalist for the multi-platinum group, the Pussycat Dolls. Their debut album, PCD, has sold nine million copies worldwide, and their sophomore album, Doll Domination, has sold 5 million copies to date. After leaving the group in 2010, Scherzinger began a solo career with the release of her debut album Killer Love. The album’s second single 'Don’t Hold Your Breath' peaked at number one on the UK Singles Chart, making her first number one hit as a solo artist.
