Chris bears a striking resemblance to Katy's ex-hubby, Tom Cruise, and he's one of only a handful of up-and-coming actors to have achieved bona fide action-star status during the '00s. So if Katie's looking for Tom Cruise part deux, Chris could be her guy. The "Star Trek" star graduated with a B.A. in English from U.C. Berkley, so he's not just a stud muffin, he's a smart cookie too. We think these two would be super sweet together. If she doesn't want him, beam us up!
