If Britney's upcoming performance [1] on How I Met Your Mother [2] seemed too good to be true, here is your first look at the pop star on the set. She's going to play a receptionist who catches Ted's eye during a visit to the doctor's office. (Fun fact: Sarah Chalke from Scrubs [3] is also making a guest appearance in the episode.) Britney's big debut doesn't air until next week, but you all can get acquainted with the fabulous show tonight when How I Met Your Mother finally comes back [4] from writers' strike hiatus!
