Ex-Busted star Matt Willis has entered The Priory drug rehabilitation centre.
According to The Mirror Willis, who had stints in rehab in 2005 and 2006, went for treatment after having a heavy partying session with Amy Winehouse in London.
The newspaper claims that Willis' fianc�e, Emma Griffiths, gave him an ultimatum � give up drugs or lose her.
An anonymous source is quoted as saying: "He [Willis] 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."
