Kim Yu-na, the reigning Olympic and world champion in ladies' figure skating, sported a black suit, tie and fedora during the exhibition gala of the 2013 World Championships in London, Ontario, Canada on Monday. She appeared 22nd out of 24 skaters and was greeted with thunderous applause before skating to "All of Me" by Michael Buble.

But Kim won't have much time to bask in the spotlight and returns home on Wednesday to begin preparations for the Sochi Olympics after some rest. She seems likely to renew her contract with current coaches Shin Hye-sook and Ryu Jong-hyun.

"I feel comfortable with them since they've been coaching me since I was young," Kim said.

Her new Olympic programs will be choreographed by David Wilson, who has worked with Kim since her debut in the senior circuit in 2006.

"I will have to be extra careful when choosing the new programs," said Kim. "I'm worried whether I'll be able to come up with a free skate program that can surpass 'Les Misérables.'"

Kim also plans to to take part in the International Skating Union Grand Prix series, where she will likely advance to the final in which the top six skaters compete. She participated in the finals during the 2006-7 and 2009-10 seasons, and earned one second-place and three first-place finishes.

Tryouts for the Olympics will likely be held through the national ranking competition in November, though Kim will most certainly be exempted. She secured three Olympic spots for female Korean figure skaters though her victory at the worlds.
