Lindsay Vonn's Ex-Husband Jokes About Tiger Woods' Masters Penalty: "Keep an Eye on Those Cheaters"

Thomas Vonn claims he reported golfer's faux pas during tournament that resulted

Jokes about Tiger Woods often write themselves.

But when Thomas Vonn, Lindsey Vonn's ex-husband, takes a crack at the golfer, it packs a real punch.

On Friday, Tiger came under fire when he made a questionably illegal ball drop, which only came to light after a TV viewer called the Masters Committee to point it out. Tiger tweeted that he "was unaware at that time I had violated any rules" but after meeting with the Masters Committee he was fine to "understand and accept" the two-shot penalty.

Lindsey, who was cheering on her Facebook official love in Augusta, Ga., throughout the tournament, only finalized her divorce to Thomas Vonn in January 2013. And Thomas, a former Olympic skier turned agent, was happy to laugh at Tiger's faux pas on the green.

"No problem Masters tournament happy to call in and help," Thomas jokingly tweeted. "You always have to keep an eye on those cheaters ;)"

Wonder if Elin Nordegren got a laugh out of that one, too?
