Slow Hands Niall Horan
You won't be hearing Sweet Child O' Mine or Paradise City on Glee any time soon.
Guns N' Roses have refused to allow the show to feature their songs.
According to Slash producers of Glee wanted to write a tribute episode based on their hits.
Slash revealed: "In the current climate of what’s going on in entertainment these days, I try to be more optimistic than negative because it’s really easy to get negative about it, but I draw the line at Glee.
"Glee is worse than Grease and Grease is bad enough," he tells EW.com "When Grease came out, I was like, 'Oh c’mon, give me a break.'
"Actually, I look at Grease now and think, 'Between High School Musical and Glee, Grease was a brilliant work of art.'"
Kings of Leon have also come out and said they don't want to ever be a part of the show.
