Oasis have blasted "ridiculous" Duffy.

Brothers Liam and Noel Gallagher have hit out at the 'Warwick Avenue' singer - who recently filmed an advert for Diet Coke - saying she was "invented".

Oasis frontman Liam said: "Duffy was alright until she opened her mouth. The music is OK until she did that stupid advert and things like that. It's ridiculous."

His brother, guitarist Noel, added: "Good luck to her, she's a nice girl but you just feel like it's been invented.

"It's like they've said, 'Amy Winehouse, she's got a black beehive, we'll do a blonde one.

"That's the problem with the musical landscape, everyone's got clipboards."

Liam recently spoke out about the technical problems which caused the opening night of the group's current UK tour to be delayed by 40 minutes.

The rockers offered fans at the Manchester show a refund and despite his annoyance, the 'Live Forever' star admitted he prefers chaotic performances because the group normally "don't do that much".

He said: "I like s**t like that, as long as no-one dies or gets hurt or gets the f**king fever because they're too cold.

"I like it when s**t happens like that because I think once you have seen Oasis once, you have sort of seen we don't really do that much."
