Older sister, slow-moving train wreck and aunt-to-be Britney Spears gives an expressionless face to the celebrity news media as she waits at a red light near her home while driving a friend back home in Los Angeles.

Is she upset because for once, pregnant Jamie Lynn is going to have a l'il mistake instead of her? Or is she merely off her medication? Overtired? Who knows.

And who's this friend of Britney's? While there may be a slight Courtenay Semel resemblance, we have no idea who this is. But it's not Sam Lutfi, thankfully.

Britney Spears looks far from pleased ... at life.
