Martin got back at Gallagher for calling him a 'plant pot' at an awards show six years ago.
He recently performed a charity gig at the Boogaloo pub in London and sung his new track Wedding Bells.
According to UK newspaper The Sun, he said: 'This is a soppy song. I apologise but it's what Coldplay is all about, and it has made me mill… very happy.
'Hey, I've got to get paid for all the abuse I get from people like Liam Gallagher.'
After finishing the track, the singer asked the audience what they wanted to hear him play and some said Wonderwall, which he then performed.
