Javine from Popstars the Rivals had a few minor hits and represented UK at Eurovision. She was later embroiled in a cheating scandal with MC Harvey while he was married to Alesha Dixon. She had a baby with him and they later split. Haven't seen her in years.Pop Idol - no one I can really remember (and briefly Darius and Gareth)
Pop Idol 2 - no one
Popstars, Popstars the Rivals - Girls Aloud, Liberty X, Hear'Say (again, briefly and the girls/Kevin Lib X still pretty famous)
XFactor - Little Mix, 1D and Leona obvs. Shayne, JLS, Alexandra Burke, Olly Murs, Stacey Soloman, Rylan are all still kicking about whether its music, TV, theatre, acting etc...
Bloody good investigative work there @Pinkii , I'm impressed!
Pop Idol 1 - Jessica Garlick represented the UK at Eurovision 2002 with Come Back and did quite well, good song.
Does anyone remember Emmie who had a hit with a cover of More Than This by Roxy Music. Made number 5 so not strictly a flop, but the follow up bombed. I didn't like her version, but I'm a big fan of Roxy Music so probably biased
