Tulisa Contostavlos' ex Justin Edwards for Celebrity Big Brother 2012?

Tulisa Contostavlos (X Factor)

Tulisa's ex boyfriend Justin Edwards has been linked to Celebrity Big Brother 2012.

Justin - Aka MC Ultra - hit headlines last month after a sex tape featuring him and Tulisa hit the web.

The X Factor judge is currently taking legal action against him, claiming £100,000 in damages for alleging leaking the video, which he denies.

The rapper is now one of many names wanted for Celebrity Big Brother later this year.

Show bosses hope that the rapper will spill the beans about his relationship with Tulisa, and the truth about the sex tape.

And with the new series of Celebrity Big Brother set to return to air at the same time as The X Factor, it'll be great promo for the show.

Other names linked to the new series include Samantha Brick, former Bachelor stars Gavin Henson and Carianne Barrow and former footie player Freddie Ljungberg.

A spokesperson for Channel 5 insisted however that all the rumours were merely "speculation".
