Jake Gyllenhaal has traded in his girlfriend for a new model. Sources say he’s moved on from Sports Illustrated Swimsuit babe Emily DiDonato to another SI stunner, Alyssa Miller. Spies tell us that Gyllenhaal and Miller were spotted at lunch last week at the Dutch in Soho before reports they’d been “making out” at Cold Process Coffee & Tea. Gyllenhaal dated DiDonato for “a month or two,” according to reports. Reps for Miller and Gyllenhaal declined to comment.
