Britney Spears was guest starring in the US tv-show How I Met Your Mother, and the show had a record of 10 million viewers (quite good for an otherwise estremely crappy show).

Britney really looked like the good ol' Britters. Fit and adorable.
I loved her in Will&Grace, that was just extremely hilarious! Keep up the good work Britney, that might be the way out for ya!
