The Brit singer might be best known for hit songs like "Smile" and "LDN," but it's her personal life that gets most people talking.
Born in London in 1985, the young Allen was a troublemaker who saw singing as a way to do something good with her life. Unfortunately, her bad behavior and dependency on drugs and alcohol hindered her from initially scoring a record deal, but thanks to social networking site MySpace, Allen’s big break came after she set up a music page to get the word out. Allen’s 2006 debut Alright, Still was followed up with the digitally-released It’s Not Me, It’s You, which debuted in early 2009.
Allen formerly dated Chemical Brother Ed Simons, but the two broke up shortly after she had a miscarriage in early 2008.
The singer wed Sam Cooper on June 11, 2011. Their daughter, Marnie Rose Cooper, was born in January 2013.
