Britney's tender moment as she picks up her son Jayden from school

Last week she was pictured looking every inch the polished popstar as she met delighted children from the Bronx.

But this week Britney Spears' focus was entirely on her own children as she picked up her youngest son Jayden James from school.

In place of the dress and heels of the stage-managed press call she was dressed in a simple tank top and jeans. But it was clear the 26-year-old had no place else she would rather be.

To the rest of the world she has many faces - troubled star, sultry pop vixen and gifted singer, but to her sons she is just mummy.

And holding her two-year-old tight as he ate a bag of sweets she looked every inch the doting mother. She was accompanied by the man who has been credited with nursing her back to full health - her father Jamie Spears.

The scenes are a sharp contrast to earlier this year, when a wild-eyed Britney lost custody of Jayden and older brother Sean Preston.

But since that time the singer's life has turned around for the better.

'I've been through a lot in the past two or three years, and there's a lot that people don't know.'

'Sometimes I think I get kind of lonely because you don't open the gate up that much, you know I mean?' she continues.

'You're guarded. You have to be that way, so I'm kind of stuck in this place and it's like: How do you deal? And you just cope, and that's what I do.

'I just cope with it, every day.'
