Stephanie Rice tweets another skimpy bikini shot

Olympic swimmer Stephanie Rice is at it again, tweeting another shot of her relaxing in a skimpy bikini.

The gold medal hopeful took the picture while tanning her toned body ahead of arriving in London.

The description of the image said just, 'Life's tough'.

German Olympic swimmer Thomas Rupparth quickly commented: "Enjoy the time. Hope you're fit for London."

Rice caused a stir recently after posting another picture of herself in a swim suit she received for her birthday last month.

She has also posted previously pictures of herself looking racy in a police woman's uniform.

The uproar caused by her recent tweet seemed over the top when comparing her tame pictures to the nude ones taken by the US athletes in ESPN's recent 'Body Issue' magazine.
