Britney Spears is apparently to guest star in an upcoming episode of US sitcom 'How I Met Your Mother'. The singer, who'll play a doctor's receptionist who becomes obsessed with the show's main character, has already been to a script reading and will film her scenes this week.
One of the show's stars, Neil Patrick Harris, told Entertainment Tonight: "I was shocked that Madame Spears was willing to come and do some acting, she hasn't acted in a while. This is a very interesting role - it will be very unlike any Britney we have seen before, and we have seen a lot of Britney recently".
