AceShowbiz - Liam Gallagher has opened up on his feud with "Coronation Street" favourite Simon Gregson after the actor allegedly "flipped me the bird."

Former Oasis star Liam told Britain's The Sun newspaper the incident took place when the duo crossed paths early in his career following an appearance at ITV Studios in Manchester, England - where the soap also films.

According to the "Wonderwall" hitmaker, he was enjoying a post show drink when he spotted Simon waving his middle finger at him as he drove past, prompting him to race after the actor's car on foot and attempt to pull the actor out of the driving seat when he stopped at traffic lights.

"I was walking down the road with my jacket on and (Simon's car) came out and he's staring at me and I'm staring at him and he's giving me looks back and I've gone, 'What you f**king looking at?,' " Liam recalled.

"And he's wound down his window and flipped the bird at me and then I've chased him down the road. And he wound his window up and drove off and I kept catching him at lights."

He added, "He was coming out of the Granada TV studios where they'd been doing Corrie and we had just been making our TV debut with Take Me and he f**king flipped me the bird. Can you believe that?"

Simon has yet to respond to Liam's claims.
