This picture clinches it: We are officially Team Jacob. “Twilight” star Taylor Lautner was spotted in his favorite Red Sox hat at the West Hollywood restaurant Craig’s on Thursday night. Lautner started wearing the cap when he was in Marblehead and Swampscott filming the Adam Sandler comedy “Grown Ups 2,” but after a trip to Fenway during production he seems to be supporting our team for good. One of Lautner’s costars in “Grown Ups 2,” Patrick Schwarzenegger, has been tweeting about college life ever since he moved into his dorm room at the University of Southern California more than a week ago. Schwarzenegger, of course, is a cousin of Conor Kennedy, who is dating Taylor Swift, who used to date Lautner. Got that?
