The singer appeared to punch someone in the front row as she performed ‘Rehab’ in the pit in front of the stage.
A video of the incident can be seen below.
The festival chief revealed she reacted after being groped by a fan.
“It was a shame what happened at the end, someone put their hands on her boob,” explained Eavis. “Come on! That’s not on. He deserved it, he put his hands on her breasts!”
However, Eavis called the singer’s set a “triumph” and revealed the incident has not put Winehouse off Glastonbury.
“It’s the biggest crowd I’ve ever seen on that stage,” he explained. “She was absolutely brilliant, she became a superstar. You know what she asked me at the end of that show? ‘Can I headline next year?’ How about that? Will she? I don’t know if her manager approves, he was standing behind her, but that’s all she said to me.”
