Name: Coleen Nolan
Famous for: Singing; reality & daytime TV
Following her former Loose Women colleague Denise Welch's CBB win in January, Coleen's taken up the challenge of spending the next two weeks in the Big Brother house.
Having initially found fame in the late '70s as one of the Nolan Sisters, a group who've been in the mood for dancing for more than 30 years, Coleen has latterly become a favourite on reality and daytime TV.
She made her first appearance on Loose Women in 2000, joined the This Morning's roster of presenters in 2001 and appeared on the first series of Celebrity Fit Club in 2003.
Since then, she's taken part in Dancing on Ice, All-Star Family Fortunes and even been regressed though her past lives on 2006's Have I Been Here Before (it turns out that she was "nervous 16-year-old debutante" in a former incarnation), a TV appearance you can enjoy all over again below:
