After reports surfaced this week that Tiger Woods’ girlfriend, Lindsey Vonn, has become fast friends with his ex-wife, Elin Nordegren, a picture has surfaced of the threesome spending time together at Woods and Nordegren’s son Charlie’s tee ball game last weekend.

The photo, which TMZ has posted, shows Nordegren sitting on a bleacher below Woods and Vonn. Onlookers say they all acted civil towards one another and at some points, even friendly.

As we previously reported, sources say Nordegren wanted to meet Vonn because she’s around her kids – they also have a 6-year-old daughter Sam – and when they met they hit it off.

“After meeting her, she found she actually liked her," a source said. “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.”

The surprising aspect of all of this is the way in which Nordegren and Woods split, as it was widely reported she smashed in his car with a golf club after finding out about his various mistresses.
