The former Oasis star explained their friendship, insisting that he is the "polar opposite" of Martin and his clean-living practices.
Gallagher told The Sun: "He's my mate and the polar opposite of me. He does yoga and doesn't smoke. I'm trying to get him to smoke but he's not having it.
''I said to him I'll do the f**king crab or the scorpion if he shares a Marlboro Light with me.
''But he's not having it. He's taller than me so he'll probably put me in a headlock, roll me into a ball and throw me into a swimming pool.''
Gallagher revealed that Martin made sure everything was perfect for their Brits performance, when the Coldplay frontman played piano throughout his hit 'AKA... What A Life'.
He added: "Chris is very thoughtful - the polar opposite of me. He likes to have things perfectly right and I couldn't give a s**t.''
Gallagher recently confirmed that his second solo album, which he has been working on with Amorphous Androgynous, will not be out until 2013.
