Britney Spears is more than ready to make her pop comeback, because she's getting "stronger" every day, according to her manager Larry Rudolph.

The Toxic hitmaker is bouncing back following a tumultuous last 12 months - which has seen her lose custody of her kids to ex-husband Kevin Federline, shave off all her hair, and end up in hospital twice.

But Rudolph is confident his young charge - who took home three gongs at the MTV Video Music Awards in September - is back on top form as she prepares for the release of her new album Circus in December.

He says, "She's definitely ready. She loves to work. She's a very strong person. Everybody goes through setbacks in their lives. (But) every day, I see her getting happier and stronger."

And Rudolph insists Spears is handling the pressures of being a working mum well - because she plans her career around sons Sean Preston, three, and Jayden James, one.

He adds, "Her kids and balancing her life with her kids is an incredible priority - the number one priority in terms of how I operate with her."
