Melbourne, January 25 : Sport stars Stephanie Rice and Michael Clarke have stripped to their underwears for a new string of advertisements.

While the ace cricketer Clarke posed for Bonds, top swimmer Rice, joined by former beau and fellow Olympian Eamon Sullivan, endorsed Davenport.

The advertisements were said to have stepped a little over what is dubbed as bizarre, especially in Clarke''s case, reports the Daily Telegraph.

The vice-captain of the Australian team apparently sheds his clothes while playing tennis with Pat Rafter, using a cricket bat in place of a racquet.

The 27-year-old then goes on to catch a tennis ball in his underwear, daring Rafter to pick up the ball with a cheeky: "Your serve, Paddy.''''

Meanwhile, Rice was snapped in her bare essentials, "wrapping" herself with Australian icons, including a flag and battered Akubra. (ANI)
