Tiger Woods' ex-wife Elin Nordegren is single once again after splitting from her billionaire boyfriend Christopher Cline.

Elin Nordegren, Christoper Cline Split

Nordegren and Cline, a 54-year-old coal tycoon, reportedly split up over the weekend, according to the New York Post. "They didn't spend enough time together," a source told the paper. "He has a thriving business and has been traveling a lot."

Following the split, Nordegren, 34, headed to the Hamptons with some girlfriends for a low-key getaway. “She flew in for just the weekend,” an insider said to Page Six. “She is single again and hotter than ever.” The group planned to head to the beach, do some shopping and indulge at the local eateries.

Nordegren and Cline first began dating in March 2013. "They can be a happy foursome now that Elin has a guy even richer than Tiger," an insider told Us Weekly in April, referring to Woods and his girlfriend, Olympic skier Lindsey Vonn.

In the years since Nordegrena and Wood’s explosive split, the couple has managed to develop an amicable relationship that centers around their two children – daughter Sam, 6, and son Charlie, 5.

“My relationship with Tiger is centered around our children and we are doing really good — we really are — and I am so happy that this is the case. He is a great father,” Nordegren, who recently graduated from Rollins College, told People earlier this year.
