Jake Gyllenhaal and Reese Witherspoon have sparked rumours that they are a couple again.

The pair became close when they met on the set of their forthcoming movie Rendition, but they split in June because Reese wanted to spend more time with her two children.

However, Gyllenhaal and Witherspoon have been spotted together on a number of secret dates recently, resulting in speculation that they have rekindled their romance.

A source told US Weekly: "Reese came to terms with the fact that she can have a relationship and spend time with her kids."

Witherspoon announced that she was divorcing Ryan Phillipe after seven years of marriage in October 2006.
