(Cover) - EN Showbiz - Christina Aguilera says her proudest moment is giving birth to her son.

The 30-year-old singer has three-year-old Max with her estranged husband Jordan Bratman. The couple separated last year, but Christina still believes their union resulted in her achieving one of the greatest feats of her life, outstripping any accolades she has received throughout her celebrated career.

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

With over ten years in the music industry, Christina now finds herself influencing other younger, newer, artists. She is now looked on as an icon by some, which she finds strange as she still looks up to so many female artists.

Its difficult to choose an idol. There are so many strong and powerful women and I really look up to all of them, she added. (C) Cover Media
