Britney Spears' mother Lynne is determined to get the singer and sister Jamie Lynn back on track - after a troubled year for the family.

Toxic hitmaker Britney went into meltdown after losing custody of her two sons Sean Preston, three, and Jayden James, two, last year - and was hospitalised for a mental evaluation in January.

And Lynne's youngest daughter Jamie Lynn fell pregnant at 16, giving birth to Maddie Briann Aldridge in June.

But the pair's mother is adamant that both girls have a bright future ahead of them.

She tells Fox's The Morning Show With Mike and Juliet, "(I would them to have) something that will really fulfill them and make them grow to their full potential. I want them to feel really good about themselves."

And Lynne isn't sure whether fame was the right path for her girls, adding: "There are certain things I would do over, of course. I always hoped that my children would fulfill their dreams and this was their dream. Certain aspects of their dreams, I would certainly rearrange or change."

But she is adamant she isn't to blame for their personal problems: "People think I was this stage mom, that I was pushing my daughters to do what they did. I was actually their cheerleader. I have never been their manager, that's never been my role. I was the one that got their coffee in the morning and (got them) out of bed."
