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 (05) 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."
