Tom Cruise, 50, appeared on
The Tonight Show with Jay Leno Wednesday to talk about his latest action film
Oblivion, in which he plays a space veteran called Jack. However, the conversation took a turn when he was joined by his
All You Need Is Kill co-star Emily Blunt, who let slip an embarrassing demand asked of Tom by his adoring female followers. When asked by the show's host which body parts Tom has been asked to sign in the past, Emily quipped: "Their boobs!" Laughing uncontrollably, Tom agreed: "Boobs!" Before revealing the racy requests Tom is given by his fans, Emily, 30, praised the action star's "passion" during filming and admitted she very much enjoyed shooting the explosive sci-fi feature with him. After initially joking "he's the worst" person to work with, Emily was quick to state: "He's the greatest. I've never actually met anyone with more enthusiasm and passion."
