Christina Aguilera and Jordan (R)

Pop star Christina Aguilera has defended fellow singer Britney Spears' parenting skills, insisting she is a great mother.

The Beautiful hitmaker - who is reportedly expecting her first child with husband Jordan Bratman - says the pressures of childhood fame have taken its toll on her pal Spears - but she is not a bad parent.

She says, "Britney is a good person and a good mom.

"She's been under so much pressure since she was a child. I don't think any of us should judge her or jump to conclusions.

"She loves her boys (Sean Preston and Jayden James) and they're turning out great."
