From Liam hitting Noel over the head with a tambourine and threatening to quit Oasis to Liam changing the lyrics of a song so they were offensive to Noel, the sibling spat has become nearly as infamous as their old band Oasis.
But the Brit-pop brothers have now thrown the world another curveball and appeared to reach some sort of Christmas ceasefire.
Younger brother, Liam, 45, wished Noel, 50, a "Happy Xmas" on Twitter, saying "looking forward to seeing you tomorrow".
Asked by a fan if he would have a meltdown on Twitter if Noel ceases to get in touch on Christmas day, he replied: “He's already reached out.”
To the delight of fans, he added: “We’re all good again”.
Liam's tweets have sparked hopes an Oasis - who split in 2009 - reunion could arise.
One said: “Please let this be it! Come on Oasis reunion!! Have a wonderful Christmas Liam Gallagher love to all your family and Noel Gallagher you're both amazing rock and roll stars!!”
Another said: “Sounds to me like an Oasis reunion is on the cards?”
One more added: “NG??? Do I see an Oasis reunion on the horizon???”
The brother’s tumultuous relationship has taken something of a more unusual turn in recent years with Liam subjecting Noel to potato-based insults, calling him a “Pouting potato” at one point.
But last month Liam confessed to missing his brother, saying he did not like going on stage without him.
He told FAULT magazine: "'I don’t want to be solo. I don’t want to do it on my own - I’m not a guitar player or a prolific songwriter."
Confessing he wanted to make up in October, he told the Sunday Mirror: "I hope we make up. Not just for Oasis but for brothers. Enough is enough now.
"I know I wind him up. I have put it out there enough times, but I think he doesn't want to know. I reckon we would have to meet up and hug it out, as they say."
