Elin Nordegren, Tiger Wood's ex-wife, and her billionaire boyfriend Chris Cline split after dating for one year.

A source told Us Weekly that the Swedish model, 34, and the 54-year-old coal tycoon started dating in March 2013 but "They didn't spend enough time together. He has a thriving business and has been traveling a lot."

Chris Cline was the first serious relationship that Nordegren had after she divorced golf champ Tiger Woods in 2010 after a much covered cheating scandal claiming he cheated on her with dozens of women.

Nordegren, 34, and coal magnate Cline, 56, live next door to each other in huge homes in North Palm Beach, an insider says they "drifted apart."

Nordegren and Woods share daughter Sam, 6, and son Charlie, 5. Chris Cline has four children from two marriages.  

According to Forbes magazine, Cline is worth $1.4 billion. Cline's Foresight Energy owns mines in Illinois and northern Appalachia. Tiger Woods is reportedly worth $1.3 billion.

Elin Nordegren got $100 million in her divorce settlement from Woods. Nordegren earned a bachelor's degree in psychology in May.

According to Us magazine Nordegren and Woods have remained friends since the divorce. Elin and Cline have gone on double dates with Woods and his girlfriend Lindsey Vonn.

Elin Nordegren reportedly fled to the Hamptons after the breakup from Cline.

"She flew in for just the weekend," a source told Page Six. "She is single again and hotter than ever."
