Britney 'didn't save' CBS sitcom

CBS has denied claims that Britney Spears' appearance on How I Met Your Mother "saved" the show.

Ratings for the sitcom were given a boost when Spears starred as ditzy receptionist Abby in two episodes. It was only after Britney's episodes had aired that CBS announced the programme's renewal for a fourth season.

However, the network's entertainment president Nina Tassler has now insisted: "It was never in danger; we just took a while to make the announcement [of its renewal]."

The show's co-creator Craig Thomas has confirmed that "the door is open" for further appearances from Spears. Her role has also been praised by the sitcom's stars Alyson Hannigan and Neil Patrick Harris.
