Australia's Stephanie Rice completed the Olympic medley double with victory in the 200 metres final in world record time at the Beijing Games on Wednesday.
Rice, 20, followed up her world record triumph in the 400m medley on Sunday when she came from behind to pip Zimbabwean Kirsty Coventry to lower her world record by 0.47secs to two minutes 08.45 seconds.
Coventry took silver in an African record 2:08.59 with American Natalie Coughlin finishing third in 2:10.34.
Rice became the first Australian to win swimming's 200m-400m medley double at the Olympics.
It was Australia's fourth gold in the pool with all won by the crack women's team.
Rice had another stroke-for-stroke battle with Coventry before just out-touching her at the wall.
Rice, the pin-up girl of Australian swimming, holds both 200/400m medley world records.
She completes her program with the women's 4x200m relay on Thursday.
Rice has rocketed to Olympic stardom after taking bronze in both the 200 and 400m medley events at last year's world championships in Melbourne.
