They may say they’re just pals, but Gerard Butler can’t stop gushing about his Bounty Hunter co-star Jennifer Aniston. “She’s vivacious. She’s just so alive inside, and that really shows through,” the hunky actor told In Touch at the comedy’s premiere in New York on March 16. Gerard, who celebrated Jen’s 41st birthday with the sexy star and her friends in Mexico’s Cabo San Lucas last month, didn’t fail to comment on her smoking hot figure, as well. “Jen does have the best legs in Hollywood!” he laughed.
