Jake Gyllenhaal, 33, has split from Sports Illustrated
model Alyssa Miller, 24, after a six-month relationship. A source told UsMagazine.com: ''They fizzled out. It happened a while ago -- before the holidays. He's back on the scene. Things were really good between Jake and Alyssa right up until he had to leave for L.A. to go shoot a movie [Nightcrawler] in the fall. Then the distance just really got to them.'' A friend also confirmed: ''They were apart for the holidays, and things weren't good with them even before that. She's very much a long-term relationship girl. He's not as much of that mind-set.'' An insider added: ''I know people are bummed, because many thought he had a chance this time.'' The former couple started dating in
June after they met at a gym in New York. The Brokeback Mountain
actor has dated a slew of fellow celebrities in the past including Reese Witherspoon, Kirsten Dunst, Minka Kelly and singer Taylor Swift.
