Kaori Sakamoto, Alysa Liu and Ami Nakai received their medals from IOC president Kirsty Coventry
American superstar Alysa Liu added Olympic figure skating gold to her world title as she beat a standout field in the women's final.
Liu came into the free skate in third place following a couple of errors in the short program, but produced a performance for the ages.
Appropriately wearing a sparkly gold dress and performing to Donna Summer, she scored a staggering 150.20 in her free skate.
It pushed her to the top of the leaderboard with an overall score of 226.79, narrowly beating Japan's Kaori Sakamoto - who Liu beat to the world title last year.
