He's just spent the last month or so holidaying with her in the US, appears in her new video (no, not that one) and even has her name tattooed on his ankle so we can't say we're too surprised to hear that Tulisa's PA also makes time to escort the singer on romantic dates.

Errrm, hasn't she heard that three's a crowd?

The X Factor judge has revealed that she is so close to bezzie and PA, Gareth Varey, that he is always by her side - and that includes vetting potential boyfriends.

Speaking on Radio 1, she said: "Gareth is a legend. He's my best friend and brother - he doesn't leave my side and supervises dates. If I started seeing a guy he'd be on the first four dates, we come as a package. He's just there."

Bet Jack O'Connell loved that, Tul.

And it seems it's not just potential love interests who have to get Gareth's seal of approval either - new friends do too.

"I only hang about with people I don't feel awkward around," she said. "I don't let many people into my circle."

S'right love. We've already got enough of our own friends anyway.
