The star speaks about what really happened during his drug-fuelled time with Oasis - and the feud that followed...

ROBBIE WILLIAMS looks set to reignite his feud with

OASIS in a forthcoming biography in which he reveals what he really thinks of NOEL and LIAM GALLAGHER.

Robbie and Oasis became friends in the mid ’90s shortly after Robbie had walked out on [a][/a]. Robbie even ended up on stage with the band at Glastonbury 1995, before relations soured and one of the most famous celebrity fall-outs of recent times erupted. Liam and Robbie Williams almost reached the point of blows, and Noel went on to blast his old pal in the press.

In a new biography, ‘Feel’, which is published on September 1 and written by Chris Heath, Robbie gives his side of the story.

In ‘Feel’, Williams confesses: “I went from (being) Noel’s mate to him keeping his distance and me being mates with Liam.”

“Liam and I just used to do shitloads of charlie and sing ‘Sgt Pepper’ to each other. But Liam was really paranoid about everything. It’s dreadfully sad for him.”

Liam then turned on his old friend, and they traded vicious insults in the press and Robbie

offered to fight him for a £100,000 charity purse before the argument cooled.

Robbie claims he got his revenge on Noel for calling him a “fat dancer from Take That” by writing a letter, never sent, along with some pies and a pair of dancing shoes on the eve of his three sold-out dates at Knebworth last summer.

Oasis played two consecutive nights at Knebworth in 1996.

The letter read: “Dear Mr N Gallagher, you said two nights at Knebworth is history. Well, I guess three is just greedy. Yours, Rob.”

“PS: Finding it difficult to find adequate support for my show. What are you doing on the 1st and 2nd? Oh, and the 3rd?”
