Tulisa's mystery man is not the actor

Skins star Jack O’Connell has dismissed rumours that he’s Tulisa Contostavlos‘s new boyfriend as ‘laughable’.

The 21-year-old was romantically linked to the X Factor judge after they were snapped partying in London – but Jack insists they’re just friends.

‘Now then, massive thankings to my MATE @officialtulisa for a top wednesday and beyond, finishing now. Take it easy PAL & maybe see you…,’ Tweets Jack, who played James Cook in the teen drama series.

‘…In USA. What a top week, u wait now mrs, I o u. My MATE (not lover, not mrs, not any wanky red top label) @officialtulisa T’raa kid!’

But the pair have obviously struck up a solid friendship – Jack yesterday took Tulisa to watch his favourite football team, Derby County – aka the Rams – in action.

And Tulisa, who split with her N-Dubz band mate Fazer in January, really got into the game.

‘C’mon U RAMS wooooiiiii,’ Tulisa, 23, Tweeted.

‘As if I went in the opposition’s box 2 start, with a derby scarf …nearly kicked off, woops wrong seats…LMFAO.

‘I dont support a a football team I support me legs n they support me,but Ive been forced 2 convert,gotta support sum1,only right..

‘Say what ya want! Cus WE WON wooooooiiiiiiiii.’
