Singer, actress and television personality Nicole Scherzinger turns 36 today. After her exit from the group Eden's Crush, Scherzinger auditioned for the group, The Pussycat Dolls, and she signed a contract with Interscope Records. The group's debut album, PCD and its follow-up Doll Domination, both experienced commercial success. Many of the group's songs became worldwide hits including "Don't Cha," "Stickwitu," "Buttons," "When I Grow Up," "I Hate This Part" and "Jai Ho! (You Are My Destiny)." Despite their commercial success, the group disbanded due to internal conflict.

Scherzinger's debut solo album, Killer Love, was not a major success on the American charts, but its singles "Don't Hold Your Breath" and "Right There" became top-ten hits in several countries worldwide. Scherzinger left Interscope Records in 2013 and signed with Sony Music Entertainment and RCA Records.

In May 2011, she joined the U.S. version of The X Factor, but was replaced in season two by Britney Spears. From 2012 to 2013, Scherzinger served as a judge on the UK version of The X Factor and won with James Arthur in her first year.

Scherzinger has been in an on and off relationship with Formula 1 World Champion, Lewis Hamilton. Rumors have swirled that the two are currently engaged.
