Someone asked Cam Gigandet this for an interview. They worked together in Burlesque.
Quote:
Q: You and Cher aren’t best friends?
CG: No, no we’re not. Christina (Aguilera) and I are, though. It’s been too difficult. Nowadays, having a family, it’s even more difficult. You work with someone so intensely for two or three months, or for however long, 24 hours a day, seven days a week. Then you’re just all of a sudden out of their life. It’s difficult to keep in touch. But one day I might get better at it.
