It’s Nicole Scherzinger!
That's right! It's former Pussycat Doll, Nicole Scherzinger.
In the early 2000s, she rose to stardom with the Pussycat Dolls and became a part of one of the most successful musical groups in the 2000s. After the Dolls disbanded, she struck it out on her own as a solo artist and even collaborated with other artists such as Diddy.
Starting in 2011, she became a part of The X Factor and acted as a judge in the show's first season in the United States and has been judging the show in the UK since 2012. She's definitely one of our favorite entertainers and her booty earns her the right to be ranked VH1's eighth Sexiest Artist of All Time.
