3am: Matt in rehab.. BUSTED STAR HITS SKIDS AFTER JUST ONE NIGHT OUT WITH AMY!

Byline: Clemmie Moodie & Danielle Lawler

EX-BUSTED star Matt Willis is back in rehab - following just one crazy night on the pop with Amy Winehouse!

The former addict was rushed to The Priory after his fiancee, presenter Emma Griffiths, gave him an ultimatum - clean up or our wedding's off.

Long-suffering Emma (below) was furious when Matt went back to Wino's pad after a night out last month... And even angrier when she saw the state he turned up in at their North London home.

Tearful Em demanded that Matt go back to the clinic before his problems spiralled out of control.

A source said: "He went too far after the night out with Amy. He was so out of it he started swinging at photographers.

"He and Emma are supposed to get married next month and have a massive magazine deal but she told him he needs to sort himself out before she becomes his wife. She made him promise that he would give up drugs and heavy drinking - and she's devastated he broke that promise. But Matt loves Emma and wants to do everything possible to win her back."

Matt was first admitted to The Priory in 2005 for alcohol abuse. Then, in 2006, he was re-admitted for his addiction to weed - at least a joint a day for eight years.

Meanwhile, we reckon Amy - who went to Sylvia Young's drama school with Matt - should come with a health warning.

Last month, we revealed how her timid ex-lover Alex Haines was sacked for alleged drugtaking. And her former tour manager Thom Stone quit after handing in a doctor's note which said heroin had got into his blood after he'd been on the road with her.

Last night, Matt's spokesman wasn't prepared to comment.

But all we can say is, get well soon, babe... we want to be throwing confetti next month not drowning our sorrows with you.
