Michael Jackson is planning a duet with his oldest son in London this July.

Michael and his son Prince Michael I are expected to take the stage together as part of the “This Is It” Tour at Britain’s 02 Arena.

A source says: “What better way to introduce his son to the music world than to have him come onstage during the most anticipated concert in history?”

“Of course nothing’s set yet, and Michael is always changing his mind.”

The 02 concert tour will be the first time that Micheal’s three children, Paris Katherine, Prince Michael I, and Prince Michael II, will see their dad perform live on stage.
