LOS ANGELES: Jake Gyllenhaal and Alyssa Miller are back together. The pair dated for six months before their romance fizzled out around Christmas. Their split was blamed on Jake’s 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, has rekindled the romance, a source tells Us Weekly. “They were still talking during the break,” a source said. “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.”–SH
