Kaplan 'Not Interested in Punishing' Britney

Britney Spears must have overcome the anxiety that kept her from attending her court-ordered deposition this week, because she was spotted smiling for the paparazzi and dancing in her car last night.

The troubled pop star, 26, cruised around Los Angeles and was seen dancing and bobbing her head to music as she sat in her car.

Now, will Britney's antics end up costing her?

"Extra" talked to Kevin Federline's attorney, Mark Vincent Kaplan, who said he's not pleased with Brit's no-show.

"This was a court ordered proceeding so it's a serious thing," he explained. "It's not like fourth grade where you get a doctor's note and it's all okay."

So will Britney face serious consequences?

"If you don't obey a court order, you can be held in contempt," said Kaplan. "We're not really interested in punishing her [Spears]…We're interested in getting facts and information that are inconsistent with her position or consistent with my client's position.”

He added, "It's going to be placed on her to tell the court why she should not be under some burden for not showing up...I'm not mad. I can go on with her or without her."

Still, it looks like Britney may get the kids for Christmas.

“Kevin would like the children to be able to experience Christmas, Christmas Eve, Christmas Day with both himself, as well as their mom, and arrangements have been made for a schedule we believe will accommodate them," said Kaplan.
