Christina Aguilera says her son is her greatest song

Christina Aguilera thinks that her son is her “greatest song”.

The singer, who has a three-year-old called Max with Jordan Bratman, says having her son was her proudest moment.

“My proudest moment was when I gave birth to my son — I always say Max is my greatest song,” she told Cosmopolitan magazine.

Christina also spoke about how difficult it is to choose an idol – because there are so many positive role models.
