Madonna gatecrashed Noel Gallagher's 50th birthday bash.
The 59-year-old singer-songwriter joined a star-studded guest list that included the likes of Damon Albarn, Russell Brand, Matt Smith and Woody Harrelson at Noel's landmark celebration - but unlike the other guests, Madonna wasn't actually invited to attend.
During an appearance on 'Alan Carr Christmas Chatty Man', the show's host asked why he wasn't invited to the bash and Noel replied: "I didn't do the guest list."
The TV star then quizzed Noel about Madonna's appearance at the birthday party.
He asked: "The only other person that was invited but turned up was Madonna. Is that true? Did she gatecrash?"
Noel - who celebrated his 50th birthday in May - then explained that Madonna attended the event after she was invited by one of their mutual friends.
The 'Holy Mountain' hitmaker recalled: "She wasn't invited but we have mutual friends and someone asked if it was OK if she comes."
Although Madonna didn't actually receive an invite to the party, Noel enjoyed her company, saying she was on "good form".
Noel said: "I was like, 'If she must'. She was there, yeah. She was on good form."
Other guests at Noel's birthday included Bono, Michael Fassbender and David Walliams.
But one notable absentee was the singer's younger brother and former Oasis bandmate Liam, who took to Twitter to vent his own frustrations.
The 45-year-old star - who released his debut solo album, 'As You Were', earlier this year - tweeted: "Re potatoes 50th he's not invited none of his family not even his own mother says a lot about the man and his part planner pair of wankers (sic)"
But more recently, Liam claimed that he and his brother have ended their long-running feud, telling his Twitter followers that they are now "all good" after Noel had "reached out" to him.
