Us Weekly reports that Elin wanted to get to know Lindsey, because the Olympic skier would be spending time with her children with Tiger; Sam, 6, and Charlie, 5.
A source told the mag, "After meeting her, she found she actually liked her. You'd think it would be weird, but Elin loves Lindsey and they talk all the time. Elin likes that Lindsey is a strong woman."
Here’s the kicker: the trio recently went on vacation with the kids. An insider says Nordegren and Vonn got along so well they left to get drinks together, leaving the pro golfer to take care of Sam and Charlie.
Tiger and Elin divorced in 2010 after it was revealed that he cheated with more than a dozen women.
Tiger and Lindsey went public with their relationship in March 2013.
