Christina Aguilera often worries she isn't being a good mother.
The 'Say Something' hitmaker - who has five-month-old Summer Rain with fiancé Matthew Rutler and Max, six, from a previous relationship - has admitted she gets "mom guilt" because she feels as though she's not doing things right by her two children, but is trying to be more relaxed about her kids.
She said: "It's hard to know you won't have all the right answers at the right times. And 'mom guilt' is the worst thing ever.
"[I've learned] to surrender and let go, knowing you're doing your very best and no one loves them, or wants what's best for them more than you."
The 34-year-old singer also struggles to balance her home life and career but insists her children are the "focal piece" of anything she does.
She said: "It's definitely not easy juggling work and motherhood, as being a parent is a full-time job within itself.
"You just have to make it work for you. My life has so many different moving parts, but my kids are the centre focal piece, and everything else shifts around them."
Meanwhile, Christina - who welcomed her baby into the world on August 16th last year - couldn't help but gush about the latest addition to her family.
She added to PEOPLE magazine: "I was speechless. She was literally like an angel ... we had an immediate calm bond, and I felt unexplainably connected to her and her spirit...
"Her smile lights up a room and I know it melts mama and daddy's hearts. She laughs a ton and is easy to make smile. She just wants to be where the action is!"
