The Oasis rocker - who has been embroiled in an infamous feud with his older brother following the band's acrimonious breakup in 2009 - admitted "it's a shame" they haven't been able to let things slide.
Speaking to Esquire magazine as part of the publication's 'What I've Learned' feature, he said: "The last time I saw Noel was at a football match about 10 years ago. It’s a shame, isn’t it?"
He added: "The good times outweigh the bad times. I think it’s best to just leave it at that."
Meanwhile, Liam revealed he's still hopeful for an Oasis reunion one day, but he warned fans not to expect the 'Don't Look Back In Anger' hitmakers to return any time soon.
He said: "I like to think Oasis will get back together, but not this week.
"The door is ajar on everything. I wouldn’t be surprised if space aliens landed tomorrow. I wouldn’t be surprised if they were already here.
"I wouldn’t be surprised if God walks among us. I wouldn’t be surprised by all sorts."
And while the Britpop legends have gone down as one of the biggest bands in the world, the AGE-year-old singer played down their legacy.
He explained: "Everyone goes on about us being the biggest. There were plenty of places where we could’ve been bigger.
"We were the biggest thing in England. And we were pretty big in Japan. But we weren’t that big in America, not at all.
"We never played stadiums in Spain. There was a lot more work to be done, so we shouldn’t have split up, because we could have made more records. It’s a shame."
Meanwhile, Liam insisted it was his destiny to be a performer.
He added: "I do believe I was supposed to be on a stage singing songs. I’ve got some good lungs on me."
