Liam Gallagher's relationship with his brother Noel is "over and done with".
He said: "Let's be clear about one thing here - this band is not a stop gap until me and our kid bump into each other. Him and me are over and done with. This is the real deal.
"I'd like to think we grow up to be friends later on but I've no time for that just yet. The way I view Oasis now is that's it like having a child from a previous relationship."
Following Noel's sudden departure from the band, Liam - who hasn't spoken to his brother since the backstage argument which led to him quitting - revealed the remaining former Oasis members decided to put together Beady Eye the same night.
He added to the Irish Times newspaper: "Noel's walked out, so it's the rest of us sitting around in a room like this one going, 'We're still a rock 'n' roll band and we still want to play', so effectively we formed that very same night'.
"I remember looking around the table that night. I was thinking to myself, 'He's a great guitarist, so is he, he's a great drummer and I'm a geezer so let's continue on without him. We don't need him'."
