Gallagher, who has made no secret of his disdain for the CLOCKS star, was particularly upset when Martin thanked Oasis for being a huge influence on Coldplay.
On picking up Coldplay's award for Best Act In The World Today, Martin said, "Liam is charming, He said some rude things, but you know, we don't have an argument with anyone. We'd like to show our undying love and respect for Oasis."
Showing his contempt, Gallagher heckled, "Knobhead! Come on, have a pop. You're a plant pot."
He later added, "That lot are all w**kers, f**k 'em."
Oasis won Best Album, for DON'T BELIEVE THE TRUTH, and The People's Choice Award at the Grosvenor House Hotel bash.
