Britney's All Smiles on 'How I Met Your Mother'

The following italicized article is from www.pagesix.com:

We've all been talking about it and now here's your first look at Britney Spears as a receptionist on How I Met Your Mother. Looking slim and sexy (from the shoulders up at least) Britney was reportedly on her best behavior last week while she filmed her cameo, although co-star Neil Patrick Harris said she seemed "fragile but professional."

Set your Tivos! Brit's episode will air on March 24.
