KELLY Osbourne cheated on her fiance during a drunken bash with friends.

The former reality star threw back cocktails at Beacher’s Madhouse on October 26 in Hollywood, where she’d gone with beau Matthew Mosshart to celebrate turning 29. But Kelly’s behavior was more like that of a randy teen.

“They had bottle service, with two bottles of Grey Goose, and she was drinking a mixed vodka cocktail,” an eyewitness tells Star magazine.

“After a bit, Kelly headed to the other side of the club. That’s when she ran into a guy she hit it off with. They were talking and giggling with each other – and then the next thing you know, she was nuzzling and kissing him.

“When Matt saw her, he flipped! He stormed over and pulled her off him. He was furious and began yelling at Kelly. He then grabbed her arm and they left the club without even saying goodbye to any of their friends.”
