Tiger Woods' ex Elin Nordegren is single again.

According to People magazine, she broke off her relationship with financier Jamie Dingman in January.

"She says Jamie's a great guy - and they're still friends - but I think it was just too early [after the divorce] for her to get serious with anyone," a friend of Nordegren told the magazine.

The pair were first linked last summer. Dingman, the son of billionaire Michael Dingman, president of international investments firm Shipston Group Ltd., manages his father's business in China. He and Nordegren's pro-golfer ex-husband reportedly share something in common - a fling with former nightlife hostess Rachel Uchitel.

Nordegren lives with her two children in North Palm Beach, Fla., and is a part-time college student working on her psychology degree.
