Jake Gyllenhaal has reportedly reunited with ex-girlfriend Alyssa Miller after the couple parted ways last year (Dec13).

The Brokeback Mountain actor dated the Sports Illustrated model for six months before their romance fizzled out around Christmas, due to his busy schedule while filming upcoming movie Nightcrawler in Los Angeles.

However, after a few weeks apart, the pair, who met in a New York City gym last June (13), has rekindled the romance, a source tells Us Weekly.

The insider reveals, "They were still talking during the break. When he was done with Nightcrawler he was spending a lot of time by himself and with his family over the holidays and he missed her."

The Hollywood star has previously dated Taylor Swift, Reese Witherspoon and another Sports Illustrated model, Emily DiDonato.
