Brit's Mom Stops by K-Fed's Cribs

A hooded and troubled-looking Lynne Spears shied away from cameras as she pulled up to Kevin Federline's Tarzana home yesterday.

It must be tough for Lynne, who had been caring for the kids, as Kev apparently has custody of the two tots while Britney does time in her third attempt at rehab. Now she's stopping by the ex's place to visit her grandbabies, Sean Preston and the elusive Jayden James.

A mother-in-law's work is never done.
