Michelle Kwan is a Chinese-American figure skater and celebrity star who only appeared in "The Good Sport", and is voiced by her real world counterpart. According to the cartoon, she went to school at Lakewood Elementary School and graduated 9 years ago from that school. Jenna was nominated as a supporting coach for many sports such as soccer, badminton, and etc., which made Francine jealous, because Francine was considered one of the most athletic at Lakewood Elementary School. She hosted the Athlete of the Year Award and handed the award to Jenna; and in Francine's dream, she pulled Francine into the TV and taught her how to figure skate, although Francine proved she didn't have the talent Kwan did.
Michelle Kwan is an anthropomorphic bear who is depicted with a pale complexion (like her real world counterpart) and long black hair tied into an elegant bun, and wears rouge lipstick, a pink women's figure skating outfit with a skirt, and a pair of white ice skating boots.
It is mentioned that she graduated from Lakewood Elementary 9 years ago, because that is an elementary school (assumingly grades K-6 or K-5), this would imply that Michelle's age in episode is the equivalent of one being in their 2nd or 3rd year of college (between 19-21 years old)
Of course, it could also be assumed that Principal Haney meant that she graduated from the district that Lakewood is in, which would mean that she is 27 years old, and graduated high school about 9 years prior
