Another punch victim of troubled singer Amy Winehouse comes forward. The "Rehab" songstress allegedly punched a man three times in a pub.

Wayne Lindsay claims that the 24-year-old Grammy Award-winning singer lashed out at him three times in the face as he stood behind her.

He told The Sun, "It really stung. I couldn't believe it. I hadn't said anything to her or touched her."

After punching the hapless man, she then stormed out of the nightspot.

A friend of the singer defended her and said "Someone behind her pinched her bottom and she reacted."

This isn't the first time Winehouse used her fist to react. During performance on the Glastonbury Festival, she was caught on cam jabbing a member of the audience with her elbow and then completely struck him seconds later. And last July 5th, she also struck a fan trying to take her picture as she was returning to her home.
