Swim star Stephanie Rice has no friends on Celebrity Apprentice

Stephanie Rice doesn't seem to be making any friends on Celebrity Apprentice.

It was a case of the Olympian vs the PR powerhouse on Tuesday morning when Roxy Jacenko took aim at fellow Apprentice contestant, Rice, on Morning Radio.

Today FM's Kyle Sandilands questioned Jacenko as to why she didn't get along with the swim star.

The ruthless businesswoman replied saying, "Stephanie doesn't want to do anything, everything is... I don't even know where to start. Stephanie, Stephanie, Stephanie, not my best friend."

This isn't the first time the Olympic gold medallist has been taken down a notch by another Celebrity Apprentice contestant.

Rice, 24, also revealed to Kyle and Jackie O two weeks ago that she "clashed" with swimming legend Dawn Fraser while filming the cut-throat reality TV show.

One-time underwear model and tabloid darling, Rice hit the headlines as a 19-year-old when she set world records at the 2008 national trials in the leadup to Beijing, while her relationship with freestyle swimmer and then-fellow world record holder Eamon Sullivan ensured she was a fixture in gossip magazines.

Revelling in the spotlight, this Brisbane-born, stripped down for photo-shoots with Sullivan and appeared in men's magazines before breaking up with the Australian shortly before Beijing.

Rice's triple Olympic triumph in Beijing, where she also won a 4x200 freestyle relay gold, cemented her status as Australia's "golden girl" and saw her carry the country's flag at the closing ceremony.

An appearance in a reality television show followed, while a relationship with Australia rugby flyhalf Quade Cooper ensured she was rarely missing from the society pages for long.

While colourful, the four years in the pool between the Games have largely been an exercise in frustration for brunette Rice, who was beaten for 200IM gold at the swimsuit-tainted 2009 world championships by American Ariana Kukors.

Her troublesome shoulder ruled her out of the Commonwealth Games in 2010 and her halo slipped after posting a homophobic slur on Twitter directed at South Africa's rugby team following their loss to Australia in a Test match that year.

The resulting uproar cost her an endorsement deal with a luxury car manufacturer and led her to make a tearful public apology.
