They say that breaking up is hard to do, but apparently not for Jake Gyllenhaal. The 33-year-old star has a bevy of gorgeous celebrity exes, and the latest among them is 24-year-old Sports Illustrated model Alyssa Miller, according to an Us Weekly report.

As told by multiple sources, there was no huge blowout that spurred the end of their six-month relationship, which began in June after the two met at the gym. Rather, the relationship had simply run its course: "They fizzled out. It happened a while ago — before the holidays." However, it sounds like Jake’s busy filming schedule and Alyssa’s modeling career contributed to the two growing apart.

“Things were really good between Jake and Alyssa right up until he had to leave for L.A. to go shoot [Nightcrawler] in the fall,” says one insider of the couple. On top of the long-distance, serial monogamist Jake may also be a bit of a commitment phobe (just ask Taylor Swift). While Alyssa is said to be a “long-term relationship girl,” the Prisoners star is “not as much of that mindset.”

While any breakup is a bummer, we’re sure it won’t be long before these two recently single hotties are back in the game. But in order to avoid some awkward workouts in the future, perhaps one of them should find a new gym.
