London, Nov 2 - Troubled singer Amy Winehouse has developed a new obsession -- working out for many hours at the gym.

The singer, who earlier got into drugs, spends three or four hours a day in the gym and her family members are quite happy with her new addiction, reports contactmusic. com.

"Everything at the moment is under control... 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," said her father Mitch Winehouse. (IANS)
