Britney -- One Hot Mama

Two things about this picture. Britney seems engaged with her kids, and she looks incredibly hot!

Brit was all smiles as she picked her children up from school yesterday. We'd like to think she brought them home for a rigorous round of homework followed by a nutritious snack.

Granddad and nanny were also on hand -- just in case.
