The singer claims he laid down vocals for most of the songs which will feature on his sibling's upcoming record because they recorded them together when the band made their final studio album 'Dig Out Your Soul'.
He fumed: "I've heard his f***ing new record 'cos I f***ing sung on half of it. When I was In America for 'Dig Out Your Soul' he swiped some off because he obviously knew he wanted to do a solo album. So he can talk all the bulls**t about, 'Oh, I was intimidated,' and all that. F***ing nonsense. Behave. He knows. The people know. And I know."
Liam - who formed a new band, Beady Eye, with the other members of Oasis after Noel walked out on the band in August 2009 - insists he couldn't care less what his brother does in the future, but predicts his concerts will be dull.
The 'Bring The Light' singer added: "I haven't spoken to him, I haven't seen him. It's very hush-hush round his camp. I put up with 18 years of that f***er so I'm not a***d with what he's doing. I'm sure it will all be very civilised and grown-up. His gigs will be like those that you can really stroke your chin at. With four rent-a-Scousers wearing shell-suits."
