Amy Winehouse stunned JAY-Z with her fiery temper at the Glastonbury Festival over the weekend (28Jun08) - after launching a scathing attack on his pal Kanye West.

The Brit has hit the headlines for attacking a reveller in the crowd at the English music festival during her spot on Saturday - but headliner Jay-Z was more put out by the singer's comments about West minutes later.

Jay-Z, who was watching her show from the side of Glastonbury's Pyramid Stage, admits he was a little upset when Winehouse turned on his "brother" during a rant in which she attempted to defend festival organisers for hiring Jay-Z as Glastonbury's first rap headliner.

She told the audience: "Imagine if it was a c**t like Kanye West! `C**ts like Kanye' - should be his next album title!"

Jay-Z tells MTV.com, "She said something about Kanye late on (in her set) but I didn't hear it and I don't agree with it. He's my brother and the biggest artist on Roc-a-fella (records) right now.

"I guess I should hook them up because he's a great guy too. I don't know what the problem is - I don't know where that (comment) came from."
