Former Busted star MATT WILLIS checked into rebab last Thursday (13JUL06) to seek help after turning to alcohol again. The British singer released his debut single UP ALL NIGHT in May (06), and reportedly hit the bottle to cope with the stress of promoting it. Willis spent the weekend (15/16JUL06) in London's infamous The Priory clinic, before checking out yesterday (17JUL06). He attended last night's premiere of STORMBREAKER in the British capital's Leicester Square. An insider says, "When Matt gets stressed about his career he deals with it by hitting the bottle. "He checked himself in on Thursday because he realised he needed help and wanted to tackle his problems before they got out of hand."
