Jake Gyllenhaal (L) and Reese Witherspoon

Reese Witherspoon and Jake Gyllenhaal have reportedly split up.

The Hollywood couple - who began dating in 2007 - have decided to call time on their relationship but sources insist the break-up is amicable.

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

Reese - who has two children, Ava, 10, and six-year-old Deacon, with ex-husband Ryan Phillippe - and Jake were rumoured to have split two weeks ago but their representatives insisted they were still very much together.

But after spending some time apart, they realised the romance was over.

The source added to E! Online: "They needed time to figure it out and they were on different coasts. When they were finally together, they talked it out and decided they're not going to be together anymore."

In October, it was claimed the couple had got engaged after the Oscar-winning actress was spotted flaunting a gold band on her wedding finger.

A source said: "Reese looked delighted, and she was definitely showing off the ring. She kept holding her finger up for people to see, she even flashed it around when she was getting in her car."
