We know she can sing, but now Cher can add Relationship Advisor to her resume.  Cher has been working with Christina Aguilera on the set of the upcoming film "Burlesque," and coaching Aguilera on love and relationships.

While working alongside Cher on the film Burlesque, Christina Aguilera picked up tips on everything from makeup to marriage.

The singer, 29, who filed for divorce from husband Jordan Bratman, 33, last month, says the one piece of advice that stuck with her was when Cher told her, "You know, honey, husbands come and go, but I am still Cher at the end of the day."
