Spotted: Christina Aguilera riding on a motorcycle with her Burlesque co-star Cam Gigandet outside of Mel's Diner in Hollywood today. The flick also stars Cher, Stanley Tucci, Eric Dane and Kristen Bell, and it marks Christina's big screen debut. Think she'll nail it? Or will this movie be to Xtina as Evita was to Madonna?
