Brittney Rose "Nikki" Cleary (born May 11, 1988, Albany, New York) is an American pop-rock singer.
Cleary first hit the pop market with the song "I.M. Me" while still using her given name. Her debut album, Everything I Wished For, was released independently under the Free Falls record label in 2002 after two years of recording. The album hit #45 on Billboard’s Top Independent Albums chart. When Cleary signed with Jive Records in the summer of 2002, they asked to change her name because they already had a Britney on their roster. Her self-titled album, Nikki Cleary was released in the summer of 2003.
She was featured on a Nickelodeon Kids’ Choice Awards record in 2003, with her single "1, 2, 3". She also performed on Nickelodeon’s All That. Cleary also did a version of "Summertime Guys", featured on the Kim Possible soundtrack. She contributed to the Mean Girls motion picture soundtrack with the song "Hated".
Nikki attended Clayton A. Bouton High School in Voorheesville, New York, and Mohonasen’s Draper Middle School in Schenectady, New York. She was married in the summer of 2009, and has four children.
