Tulisa should stay away from Jack O'Connell

Tulisa Contostavlos has certainly been making the most of life as a singleton.

She’s been linked to a number of hotties since her split from boyfriend Fazer two months ago, but Now can reveal that there’s only been one man she’s grown close to: former Skins actor Jack O’Connell.

Tulisa, 23, set tongues wagging last week when she Tweeted that she was seeing a new man – a few days after she and Jack were spotted looking loved-up on a night out.

And although Jack, 21, has tried to scotch rumours of a romance by Tweeting: Boyfriend? ME?’, our sources tell us that the pair are definitely together.

The whole thing with Jack is more serious than either of them are letting on,’ says an insider.

They’ve been friends for a while but recently they’ve become a lot closer. Of all the guys Tulisa’s been linked to, she’d most like to have a proper relationship with Jack.’

However, Tulisa had better keep her guard up – Jack‘s a self-confessed heartbreaker who admits he isn’t good boyfriend material.
