Jessie J has thrown her weight behind a possible collaboration with X Factor judge Tulisa Contostavlos.

The singer told the Daily Star that the duo have discussed writing a track together.

The collaboration would channel the pair's feminist leanings and be a "big girl power anthem". She said:

"I'd love to do a track with Tulisa. We've talked about writing a song like Do It Like A Dude together. A big girl power anthem because we are both feminists. I popped in to see her in her X Factor dressing room for two minutes and ended up staying for two hours. We just get on really well and have such a laugh, plus she's got a great bum which is fine with me."
