When Nordegren discovered that Vonn would be spending time with her children, she apparently reached out to the Olympic skier so they could get to know each other. Elin reportedly liked that Vonn was a "strong woman," and that proved to be the start of a happy friendship between the two.
The source adds that the whole group recently went on vacation together, and that the fellow blondes occasionally took off on their own to grab drinks together, while Woods stayed with the kids. "Lindsey is really good for Tiger. She's strong, opinionated, and keeps him in line," the source explains. "Elin found that they are very similar and have a lot in common. They laugh and talk like they have been girlfriends forever."
