Dunzo! Jack Osbourne‘s marriage to Lisa Stelly is over. She filed for divorce on May 18, and now In Touch is exclusively reporting that Jack, 32, cheated on Lisa, 31, with Kayti Edwards, who is Julie Andrews’ granddaughter.

Jack and Kayti were friends years ago and recently reconnected. In Touch obtained an exclusive photo of the pair outside a hotel in LA on April 11 (pictured below). “It was the Courtyard by Marriott,” an eyewitness tells In Touch. “Jack seemed nervous and was looking around a lot.”

According to a source, Jack and Lisa, who were married for six years and share three daughters (Pearl, 6, Andy, 2, and Minnie, 3 months), have been fighting a lot in the months leading up to the split.

Kayti’s rep declined to comment, while Jack’s rep denied the story.
