Liam Gallagher Planning Oasis Tell-All

Rocker Liam Gallagher is preparing to tell all about the sibling rivalry that tore Oasis apart - he's contemplating writing a film or a book based on his memories in the band.

The singer recently launched his own film production company, In 1, and he's in the process of turning Richard DiLello's book about the last days of the Beatles into a new movie.

Gallagher is planning a similar venture based on Oasis - although he's yet to decide if it will be a written or filmed project.

But the hellraising star may encounter some difficulties recalling his early days in the band he founded with brother Noel Gallagher - because his memory is fading.

He says, "Yep, without a doubt. (I want to document the memories) very soon, before I forget them all."

Noel quit Oasis last summer (09) after an argument with Liam at a concert in Paris, France and the pair has not spoken since.
