Britney Gets into the Skin Trade

For someone who's in need of constant supervision, Britney Spears' new sitcom spot is just a smidge ironic – she'll be working in a doctor's office.

"How I Met Your Mother" creator Craig Thomas tells that Brit is playing a receptionist at a dermatologist's office who falls in love with the main character, Ted, when he comes in to have a tattoo removed. Thomas says he and his writers rewrote the show in 40 minutes to work Brit into the story.

Meanwhile, what was "Mother" co-star Neil Patrick Harris' reaction to the news? "I was shocked that Madame Spears was willing to come and do some acting," he tells ET.
