Before Wednesday night's festivities, actor Jackie Chan was spotted at the Sports Club L.A., the ritzy health club at the Washington Ritz-Carlton. Chan was using an elliptical machine, we hear.

Chan, attending with his publicist Phillip Button, joins big names like Presidents Bill Clinton and Jimmy Carter, Vogue editor Anna Wintour, cellist Yo Yo Ma, figure skater Michelle Kwan, Barbra Streisand and fashion designer Vera Wang for President Obama's State Dinner with Chinese President Hu Jintao.
