Christina Aguilera works it while she films scenes for her upcoming movie Burlesque on Hollywood Boulevard in Los Angeles.  Christina co-stars with, among other stars, Cher who has had high praise for Christina:

“I’m shocked but she’s really good. The other day we were hamming it up so badly, so old, like vaudevillian. She was keeping up! She was hot. Her game is good

In between takes Christina looks like she could use some sleep.  Maybe she had a wild Valentine’s Day weekend?
