Britney Spears Goes to Pick Up the Kids at School

Yes, we know Sean Preston and Jayden James are 2 and 1. Read on.

Britney Spears is certainly no stranger to ... stranger and stranger behavior.

But a recent Us Weekly account of her January 7 antics is odd ... even for her.

Reportedly, the scantily clad (no pants?) star showed up at a Beverly Hills elementary school, saying she was there to pick up someone else's kids.

Spears parked outside the school about 3 p.m. and spent 10 minutes chain-smoking and talking to herself, waiting for classes to let out.

"She was rambling and confused," says a witness, who approached Spears to ask if she was OK. "She said, ‘I'm here to pick up my kids.' But then she said, ‘They aren't my kids; I have a new attorney, and I came to pick them up for her.'"

Far from sane, Britney Spears dropped by a local school.

Perplexed (and with good reason), the witness says, "All I could think was, 'Who in their right mind would let her pick up their kids?'"

As children began to leave for the day, Britney caused a commotion â€" "It became the talk of the school. Some of the kids were freaked out," says a school source. She was directed to a more secure entrance around back.

But before getting back into her car and driving off (thankfully, without any kids), Britney chatted up the female witness: "She said, ‘You're so nice. You should give me your number. I don't have many friends.'"

But what about Alli Sims? Chad Hardcastle? Sam Lutfi? Oh, right, all her "friends" are just sponging off her. Otherwise, they might get her help.
