Athlete Lindsey Vonn and celebrity ex-wife Brooke Mueller couldn't be more different in terms of personality, but put them both in a room and we'd be making social faux pas all over the place.

Vonn is an Olympic skier with three gold medals under her belt, yet she still thought it would be a stellar idea to start dating scandal-ridden golfer Tiger Woods -- and to announce that to the public with creepy portraits. That weirdness aside, she is also one of only two female skiers to win four World Cup Championships and, during the 2010 Winter Olympics, was the first American woman to ever take the gold in downhill.

Mueller is not doing nearly as well as Vonn, having lost custody of her two boys with ex-husband Charlie Sheen after being sent to rehab for the 21st time. (Not a typo.) The kids are currently being looked after by Sheen's other ex, the far more responsible Denise Richards.
