Britney's second sitcom appearance tonight and a third...?

A sneak peek at tonight’s return of Britney Spears to the sitcom “How I Met Your Mother,” from CBS.

Three times might be the charm for Britney Spears and How I Met Your Mother.

With Spears making her second guest appearance on the popular CBS comedy, the shows co-creator Craig Thomas says tonight’s episode was written to leave the door open for the pop singer to make a return appearance next season.

She was better than the first time and I think the fans will enjoy it because her return answers a larger mystery set up earlier in the series, Thomas said. So theres a good plot reason why shes there. And when people watch Britneys second appearance on the show theyll see that the door is still open for her to come back.

Spears first visit resulted in Mother hitting its highest rating ever. The show has since maintained an elevated audience level compared to last year. Once considered on the bubble for a fall renewal, the critically acclaimed comedy is now considered a lock to return next season.
