Ukrainian TV presenter Vitalli Sediuk managed to get into the ceremony without a ticket, insiders told The Hollywood Reporter.
Sediuk walked the red carpet and eventually found a place to sit near Justin Timberlake and Jessica Biel - a seat which one source claimed was originally earmarked for Adam Levine of Maroon 5.
He then went up on stage as Adele stepped forward to make her acceptance speech for the 'Best Pop Solo Performance' Grammy, saying: "It's such an honour to receive this award. I love you, Adele."
Sediuk was waved off stage by Jennifer Lopez within seconds of his stage invasion.
The 1+1 host was detained by security backstage, then arrested on suspicion of trespass and held in jail overnight. He will reportedly face charges in court next month.
Sediuk's previous stunts include trying to kiss Will Smith on the red carpet at the Men in Black 3 premiere and presenting Madonna with hydrangeas at the Venice Film Festival - a gift which the singer was filmed rejecting.
