Britney Spears as Abby
Britney Spears was also a fan of “How I Met Your Mother.” The singer requested to be in the episode that introduced Stella Zinman, a character the writers had big plans for. They were worried she would want to play Zinman, but fortunately, Britney decided she wanted to play Abby. Her character was a receptionist at Stella Zinman’s dermatology, who had a massive crush on Ted.
