(Cover) - EN Showbiz - Christina Aguilera's son doesn't like seeing other people touch her.

The 30-year-old songstress is mom to three-year-old Max, her son with ex-husband Jordan Bratman, and their mother/son bond is an intense one.

Christina has revealed the little boy dislikes seeing other people touch her, especially when the blonde beauty is being prepared to go on stage by cosmetic artists.

"He's very protective... when I'm getting my make-up done, he's like, No! Don't touch!'... he's very protective of momma," she beamed during an appearance on US talk show Jimmy Kimmel Live! last night.

Christina is proud to combine motherhood with a successful pop career. The star is in the process of planning the Bionic Tour which she initially scheduled for last year to promote her hit album of the same name. She isn't sure how Max will cope with seeing his mom pampered and preened.

"It will be interesting to see how he reacts [when we go] on tour," she smiled, with host Jimmy quipping that it should be called "The Don't Touch My Mommy' Tour'".

Christina also explained what a talented musician Max is becoming. Apparently the youngster has shown an eagerness for drumming, with Jimmy warning Christina she could have a future Justin Bieber on her hands.

"Uh oh, that's what happened with Justin Bieber, you be careful!" he laughed.

"The next thing you know, you'll be following him around the tour, saying Don't touch my baby!'" (C) Cover Media
