Is Jake Gyllenhaal Dating Another Swimsuit Model?

Jake Gyllenhaal sure moves quickly!

Before we could even say "string bikini," it looks like the "End of Watch" actor has ditched his rumored girlfriend, model Emily DiDonato, in favor of another "Sports Illustrated" Swimsuit Issue stunner, Alyssa Miller.

The 32-year-old hunk was spotted making out with Miller, 23, at the Cold Process coffee shop at Pier 57 along the Hudson River in New York City.

According to an eyewitness, the loved-up duo couldn't get enough of each other and were very affectionate when they weren't locking lips. In a photo snapped by our source, Gyllenhaal kept his look casual in a blue T-shirt and a black baseball cap, while his new lady friend rocked an all-denim ensemble.

Whether these two are indeed an official item is yet to be determined, but they definitely have one thing in common: They're both Yankees fans.

The Guess model, who, according to Twitter, had to hit the road this week for work, tweeted a snap of a Yankees baseball cap with a heart and the caption, "Bringing NY with me." Her baseball cap is almost identical to to the one Jakey G regularly wears around town.

One has to wonder if that cap is actually hers or if it really belongs to another Yankees fan…
