Reese Witherspoon and Jake Gyllenhaal's brief romance is reportedly over. "They just recently broke up," says a source close to Witherspoon. "It's totally and completely over. Reese was the one who had to do it. She just got out of a divorce and was so concerned with her family, she just didn't have the time for him and he really demanded that. They're still friends. Things are fine, but it was a clean break - [with] no chance of getting back together." Reps for Gyllenhaal and Witherspoon have not commented. The pair first hooked up while doing reshoots for the film Rendition. "Jake went and reintroduced himself to Reese," says an insider. "Things slowly progressed, but it was never something she thought would happen from the start. She just kind of developed this little crush over time."
