Reese Witherspoon and Jake Gyllenhaal really over?

Reese Witherspoon and Jake Gyllenhaal know how to quit each other.

The couple is no longer together.

Sources confirm that the two decided to end their relationship about two weeks ago. People magazine actually reported the split back then, but reps for both stars insisted they were still very much in love.

Reps are not commenting this time around.

So what went down? Read on...

"They needed time to figure it out and they were on different coasts," a source says. "When they were finally together, they talked it out and decided they're not going to be together anymore."

One source insists it's completely amicable. "There are no other people involved," the source said. "The relationship just ended. It just fizzled. But they also wanted to be careful and private about it because of Reese's kids."

claiming that Gyllenhaal was planning on popping the question. (FYI: Gyllenhaal seemed perfectly happy when we saw him just three days ago at Spike TV's Video Game Awards in downtown L.A.)

Gyllenhaal, who will turn 29 on Saturday, and Witherspoon, 33, never talked publicly about their romance. Unless you count gushing over Jakey's kitchen skills.

"Jake is a great cook," the Oscar winner told InStyle magazine in October. "He does a lot. We spend the weekends outside L.A, in Ojai, where I have a farmhouse. We have chickens and we grow cucumbers and tomatoes. I love it."

Earlier this month, Gyllenhaal made headline news when he used the g-word while promoting his new movie, Brothers.

"I've learned so much from the kids in my life, and somehow they just become the center of your life and the way you look at things," he reportedy told Grazia Australia. "Obviously I exist in my girlfriend's world and my sister's world in a different way, but it's opened my heart and I feel much more grown up and want to be grown up as a result of it."

Even though they had no scenes together in the 2007 drama Rendition, they apparently fell for each other while making the movie.
