Matt JayMatt JayEx-Busted star Matt Jay has reportedly cut off his friends - in order to battle his booze problems.

The 22-year-old has banned phone calls and visits from pals including former bandmate James Bourne, according to the Daily Mirror.

The only person he is staying in touch with is said to be on-off girlfriend Emma Griffiths, an MTV presenter.

Matt checked into The Priory last week and fears many of his old friends could prove a bad influence while he begins to kick his drink habits.

A source told the paper: "Matt's phone is turned off and no one can get hold of him.

"Obviously, James is really worried about him but Matt's therapists think isolation is for the best.

"The only person he has allowed to visit him is Emma.

"Contrary to what has been reported, it was Em who dropped him off at the clinic and she'll pick him up when he's finished there."
