Britney to Guest Star on "How I Met Your Mother"

Remember Britney when she looked like this?

I do. Did you hear she's going to do a guest role on "How I Met Your Mother?" I love that show even though I never watch it. I'll be glued to the tv (or at least my TiVo the next morning...or You Tube) to see her on the CBS sitcom.

Are you curious?
