Crushin' it! Tom Cruise is tackling everything from his own stunts on the set of Mission: Impossible 5 to his on-set assistant Emily. Sources reveal in the new issue of Us Weekly that the actor, 52, has a crush on the 22-year-old.

"He's always flirting with her," a source tells Hot Stuff of Katie Holmes' ex-husband. "Most people on the film have noticed how into her he is," the insider adds.

Cruise, however, is attempting to keep his focus on his role until the two can have a formal date. "He's already asked Emily to go out to dinner with him, on a date, when they're done shooting," the source says, adding that they've "never seen him crush on anyone so hard!"
