LOL! Lindsey Vonn's ex-husband Thomas Vonn showed an odd sense of humor about his ex-wife's very public relationship with pro golfer -- and notorious womanizer -- Tiger Woods, in a pointed tweet on Saturday, April 13.

Woods, 37, came under fire on Saturday after a television viewer reportedly called in a violation on the green from Woods' play on Friday. Officials launched an investigation into the game's footage, and Woods was consequently penalized two strokes.

"I didn't know I had taken an incorrect drop prior to signing my scorecard," Woods claimed on Twitter at the time. "Subsequently, I met with the Masters Committee Saturday morning."

Thomas, who was married to Lindsey for four years before the pair decided to call it quits in November 2011, couldn't resist getting in a jab at the pro golfer while he was down.

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

No word yet on whether or not Lindsey, 28, finds his quip funny. The Olympic gold medalist and Thomas -- a former Olympic skier-turned-agent -- finalized their divorce in January 2013, just two months before she and Woods went public with their romance.

The injured skier was photographed in Augusta, Ga. earlier last week, cheering Woods on from the sidelines.
