Traveling the world to try and help boost box office numbers, the stars of "Burlesque" got all dressed up for their movie's premiere in Madrid, Spain on Thursday night (December 9).

Held at Callao cinema, Christina Aguilera turned up in a sexy LBD as she joined alongside co-stars Cher, Cam Gigandet and Kristen Bell, as well as director Steven Antin.

Aside from her film promotional efforts, reports tell that Miss Aguilera will be jetting back to the States to partake in good friend Nicole Richie's wedding with Joel Madden.

Allegedly set to perform a song at the sure to be fancy affair, a source told press of Miss Richie's plans: “She’s keeping the dress a secret and hasn’t even told her bridesmaids who the designer is. Christina, who ironically is going through a divorce, will be performing a song. She has been a good friend and wants to be there for Nicole.”
