She's killing in the fashion stakes, airing her sexual innuendos on national television, coining the term 'Jah-mazing', and responsible for both James 'effing' Arthur and Rylan 'let's have it up' Clark.
Here are ten things we found out about our newest American import with the tongue-twister surname.
1. Nicole Prescovia Elikolani Valiente was born on June 29, 1978, in Honolulu, Hawaii and raised in Louisville, Kentucky. Her father is of Filipino descent and her mother is of half-Russian, half-Hawaiian descent. Nicole took her stepfather's surname after he adopted her.
2. Prior to worldwide fame, Scherzinger got into acting and has appeared in episodes of television shows such as My Wife and Kids, Sabrina the Teenage Witch and How I Met Your Mother. Most recently she sank her teeth into the role of Lily Poison for 30 seconds in Men in Black III.
3. Classically-trained Nicole first came to international attention as lead vocalist of the Pussycat Dolls, a former burlesque troupe, along with the blonde one, the other one, the other one's friend and the one currently in I'm a Celebrity... Get Me Out of Here! The group shot to fame taunting men about their average girlfriends and politely suggesting they be replaced.
4. She has a penchant for winning things. In 2001 she starred in the WB television show Popstars where she won as part of a group named Eden Crush. In 2010, Nicole won Dancing with the Stars with her partner Derek Hough. This year she is the first ever X Factor judge to have all her acts in the quarter finals... yes, Rylan (not Ella) is in the quarter finals.
5. Scherzinger is credited with creating One Direction from rejected singers Harry Styles, Zayn Malik, Niall Horan, Liam Payne and Louis Tomlinson when she appeared as a guest judge on the seventh series of The X Factor. Whatever happened to those boys..?
6. While on a hiatus from the Pussycat Dolls in 2007, she released tracks from her upcoming debut album Her Name Is Nicole. They were poorly-received, with the album release being pushed back three times and eventually shelved.
7. The Black Eyed Peas frontman will.i.am approached Nicole to join the group before Fergie; however, due to her commitments to then-group Eden Crush, she declined.
8. Originally a judge on the first season of X Factor USA, Nicole came in second with her Over 28s act Josh Krajcik. She caused controversy in week 7 when she took the vote to deadlock between 13-year-old favourite Rachel Crow and R&B crooner Marcus Canty. Crow was eliminated in a shock reveal and broke down on stage. Scherzinger was visibly shaken as she was booed. Overlord Simon Cowell booted her and other judge Paula Abdul at the end of the season.
9. This year, Scherzinger publicly revealed her eight-year struggle with bulimia, explaining how during her time in the Pussycat Dolls, "I just hated myself. I was in a group but I never felt so alone in my life... I never did drugs, but hurting myself was my addiction. The music is what saved me. That's the only thing I can trust."
10. She is currently dating Lewis Hamilton and has been on and off with the Formula One World Champion since 2008. She has also been linked in the press to Rihanna-botherers Chris Brown and Drake.
