Christina Aguilera has ''two sides'' to her life.

The 'Ain't No Other Man' hitmaker, who has six-month-old daughter Summer Rain with fiancé Matthew Rutler and seven-year-old son Max with ex-husband Jordan Bratman, says her children's happiness means everything to her and refuses to let her career affect them.

Asked what she loves most about motherhood, she said: ''The best thing is seeing my children's smiles everyday - knowing that they are happy makes me happy. We love to just get to lay in bed, cosy under the blankets and watch classic Disney movies. There are two sides to me, which I like to keep very separate. There is a performing Christina, and then there me as a mom. It's important for me to wear these different hats so I don't bring work home with me.''

But the blonde beauty credits her children for inspiring her to be more creative.

The 'Voice' USA mentor said: ''My children constantly inspire me. And I love being at home and cuddling with them in my sweatpants. I learn so much from them, and every day is a new and fun adventure. I couldn't be more lucky to have Max and Summer, they are the lights of my life. Max is such an amazing older brother! I couldn't be more proud of him. He really has a nurturing side to him and loves being Summer's big brother.''

The 'Your Body' hitmaker hopes to be a good role model for her daughter.

She told E! News: ''I want her to know that she always has a voice, that she should never be afraid to speak her mind and that her opinion is valid. And I want her to know and feel more than anything that love surrounds her.''
