So much for a poker face.
Tiger Woods clearly couldn't disguise his enjoyment over the weekend while participating in a poker tournament that bears his name, Tiger's Poker Night, an annual event presented by the World Poker Tour benefiting the Tiger Woods Foundation.
And who can blame him? After all, lovely girlfriend Lindsey Vonn, decked out in a beautiful blue dress, was on hand for support.
In fact, a source tells E! News that Vonn was never far from her man's side. Not to mention, Vonn's equally attractive sister Karin also attended.
At one point, while talking Woods up to reporters, Vonn was asked if the golfer would prove victorious.
"He wins everything," she said.
Unfortunately, Woods wound up being the first to lose.
The $10,000 buy-in tournament took place at Moorea Beach Club Beachside Casino at Mandaly Bay in Las Vegas.
In addition to Woods, other famous faces who took part included Mekhi Phifer, Mark Cuban, Kid Rock and L.A. Clippers star Chris Paul.
