Retiring star Kaori Sakamoto signed off in style by claiming women¡¯s world figure skating championships gold for the?fourth time?in Prague on Friday.

The 25-year-old Milano Cortina Olympic silver medalist marked her farewell to the ice with an elegant, charismatic routine to Edith Piaf¡¯s ¡°Je ne regrette rien,¡°?earning personal bests of 158.97 in the free skate and a total score of 238.28.

¡°There are no regrets at all, I can say goodbye with this performance,¡± said Sakamoto.
