Wino Was "Sober As A Lamb?"

Whaaaat?

Amy Winehouse attended her father Mitch Winehouse‘s birthday party and reportedly behaved herself the whole time!

In addition to singing “Happy Birthday” and some songs from her own catalog, the singer thanked her father for his support and socialized with guests, even signing some autographs. An insider revealed:

“She was on top form. A few peopled wondered whether she’d behave. She didn’t turn up steaming drunk and held her own all night.”

Good for you Wino!

Except the party was being filmed for Mitch’s documentary so that was the real reason she wasn’t hitting the bottle!

Oh well, we’ll take what we can get!
