Singer Amy Winehouse is addicted to exercise.

The Rehab singer, who has spent the past year drug-free following her public battle with addictions to heroin and crack cocaine, spends hours working out every day but her family think this is a positive step.

Her father Mitch Winehouse told BANG Showbiz: "Everything at the moment is under control. Sometimes - and I'm not talking about Amy - but sometimes other addictions come after another addiction.

"One of Amy's positive addictions is she's got her own gym. She's in the gym three or four hours a day. I mean boy is she fit - really, really fit. So that's a really positive addiction.

"But addictions can come in groups. It can be buying stuff, buying stuff that's not necessary. She's been through that as well. The whole process is one of recovery."

Winehouse spent several months earlier this year living on the Caribbean Island of St Lucia to escape her demons and work on her new material.

Although she has always been supported by her close-knit family, Mitch said most of Amy's recovery is down to her own determination.

He explained to BANG Showbiz: "We've got a wonderful family. It's been difficult, but what you've got to realise is Amy's the one who decided to change. Whatever I said at the time would go in one ear and out the other. It was her decision to give up drugs. She was the one who started the process.

"She was the one who carried it all the way through and we encourage her and help her in any way that we can. But you know, not enough recognition is given to her. As a family we just did what we were doing - being a family.

"She lost her way a little bit, she did. I think that's a fair way of putting it but now she's found her way back again, and that's great."

Meanwhile, the former taxi-driver has revealed Winehouse had her recent breast enlargement operation because her boobs were "saggy".

He explained: "I don't think the boob job was about confidence. I think that when she lost all that weight, the weight never came back on her boobs and they were saggy. So whatever the reason is, she looks great now."
