The outspoken 'The Voice' judge admitted to allowing Max to do "everything", whether that's playing with "zombies and monster trucks" or dressing up in her clothes.
The singer believes a liberal approach is best when teaching her four-year-old how to behave, explaining that she doesn't believe in having separate toys and fancy dress outfits for boys and girls.
She's certainly got a wealth of costumes from years of gigs and tours for Max to choose from should he feel like playing dress up. The 'Beautiful' singer said:
"Max is obsessed with zombies, trucks and video games at the moment! But sometimes he wants to try on one of my dresses? I let him do everything".
Currently sporting long pink locks, Christina clearly believes it would be hypocritical to dictate what colour her son would like his hair to be:
"If Max wants to dye his hair blue tomorrow, he could do it," she said. Can't argue with that!
