Hollywood superstar Tom Cruise only agreed to do all of his own stunts in upcoming movie Mission: Impossible 3 after getting permission from pregnant fiancee Katie Holmes.

The Top Gun actor proposed to Batman Begins beauty Holmes, 16 years his junior, in Paris last summer following a whirlwind romance, and they are set to wed later this year after she gives birth to their first child.

Cruise says: "She trusts me. She loves me. We show her the cut footage of my stunts and she digs it. She's fun. That's why I'm marrying her."
