Since When Did #BeefwithRice become #BeefwithMitcham?

Stephanie Rice as the gold medal-winning, all-Aussie girl.

Over the weekend, Australian Olympic gold medalist swimmer Stephanie Rice got excited when the Wallabies beat South Africa in rugby. Much like an excited teenager, she tweeted a ball field taunt:

Before this tweet, it was safe to say that most of the world didn't know this Aussie golden girl who had endorsement deals with Jaguar, underwear companies, and a sexy spread in FHM magazine. She had been rumored to be romantically linked to Michael Phelps among others, but her international profile wasn't excessively high.

All of that changed, and not in a good way, with this single tweet. Rice quickly apologized and deleted the offending tweet, but the damage had been done.

Almost immediately out rugby star Ian Roberts condemned her in the press saying, "She is an idiot ... and anyone who continues to endorse her as an athlete is an idiot as well," said Roberts.

Out diver Matthew Mitcham took to Twitter and Facebook to defend Rice, whom he's known for two years.
