The Swedish model, 34, and the 54-year-old coal tycoon began dating in March 2013, marking the first serious relationship for Nordegren since her split from golf champ Tiger Woods. (Nordegren and Woods, 38, finalized their divorce in 2010 following his monumental cheating scandals.)

As Us exclusively reported, Nordegren and Woods -- who share daughter Sam, 6, and son Charlie, 5 -- have remained amicable since the split. In fact, the exes have gone as far as going on double dates with Woods and girlfriend Lindsey Vonn.

"They can be a happy foursome now that Elin has a guy even richer than Tiger," an insider told Us in April. According to the source, Nordegren found that she was very similar to Vonn, and they would talk like they've been "girlfriends forever."
