Britney to Appear at Kids Choice Awards?

Hot on the heels of her turn as a ditzy receptionist on CBS sitcom How I Met Your Mother, OK! has learned that Britney Spears may be making another high profile show-biz appearance — this time on the orange carpet of the Kids' Choice Awards on March 29!

Britney's reps have yet to confirm the report, but insiders tell OK!, "It's supposed to be top secret, but everyone is already buzzing about it," the source says. "Her sister, Jamie Lynn, made such a splash at the event last year, Brit knows that she'll get as much, if not more, attention if she shows up this year."
