Amy Winehouse clearly has one of those personalities. No sooner has she managed to sort out her drug addiction (though she's obviously having a bit more trouble quitting the booze) than she's developed another obsession.

But don't worry folks, this time her addiction might actually make her feel better.

According to dad Mitch, Amy is now addicted to exercise and reportedly spends up to four hours a day in the gym.

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

And he's definitely NOT talking about Amy there, okay?

Mitch continued: "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."

We're guessing some sort of religious cult will be next on the list.

But it's nice to hear that Amy's doing well, though we could have done without her dad discussing her boobs.

"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," he explained.

TMI, Mitch, TMI.

We have to admit Amy's looking better these days, but some celebrity boob jobs were definitely on the unnecessary side...
