junkies birds of a strung-out feather really do OD flock together.
Now that her husband, Blake Fielder-Civil, is in jail, Amy Winehouse seems to be spending more time with Pete Doherty - and her father is not happy.
In fact, seeing the often-arrested Babyshambles singer out with his daughter made dad Mitch Winehouse go berzerk, he admitted to Grazia magazine.
"I do worry about people like Pete Doherty. He's a scumbag," a distraught Mitch Winehouse said. "I flipped when I saw him sitting with Amy backstage at her Brixton gig. I went crazy. My wife thought I was going to have a heart attack."
Some sources reported that Pete Doherty was present when Amy Winehouse overdosed on drugs in August. Regardless, they are hanging out a lot nowadays.
The diminutive jazz-pop diva, 24, has struggled mightily since her husband, Blake Fielder-Civil, was arrested for alleged witness tampering in November.
She also canceled all 2007 shows, and mother Janis Winehouse wrote an open letter published by the media, begging Amy to come home and get clean.
"I know the real problem here is that she's depressed about [Blake Fielder-Civil] being in prison," Mitch Winehouse said. "I wasn't in favor of the marriage, but they are married and I will support them. And he's shown while he's been in prison a level of maturity that he didn't have before."
While admitting to the magazine that Amy is "not very well," Mitch Winehouse said he can't force his daughter - who was recently nominated for six Grammy Awards for her smash hit album, Back to Black - into rehab.
"Believe me, my first instinct is to get hold of her, pick her up and take her back to my house and lock her away," he said. "But I've spoken to the finest drug counselors in the world, and they've said that is exactly the wrong thing to do."
