Tiger Woods has moved on to girlfriend Lindsey Vonn and while you'd expect the two to be at each other's throats, it is actually just the opposite. They're actually very close friends.

The Happy Couple: Lindsey Vonn Supports Tiger Woods

The odd couple, according to Monday's Us Weekly, became friends after Nordegren, 34, chose to get to know her for the sake of her kids with ex Woods, 38; Sam, 6 and Charlie, 5.

An insider revealed to Us, "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."

Vonn, 29, and Olympic medalist ski racer and four-time World cup champion, clearly likes Nordegren too. So, are they becoming BFF's?

The source adds that the whole group went on vacation together and the blondes often took off to grab drinks while Woods stayed with the kids.

"Lindsey is really good for Tiger. She's strong, opinionated, and keeps him in line," the source said. "Elin found that they are very similar and have a lot in common. They laugh and talk like they have been girlfriends forever."

From one Woods woman to another, they probably have a lot to talk about.

Nordegren finalized her divorce from Woods in 2010 after he cheated on her with a dozen women. Vonn and the golf legend publicized their new romance in 2013.

"We're athletes, so I guess we have something in common there. We met at his charity event in Vegas, Tiger Jam, and, yeah, we were friends for a long time," she told David Letterman in November. "I don't know...we just kind of relate really well to one another."
