British funnywoman Miranda Hart is ending her hit sitcom Miranda with two special Christmas episodes this year (14).

Hart writes and stars in the award-winning comedy, which has attracted up to 12 million viewers and is one of most watched shows in the U.K., but she has now revealed she is bringing the curtain down for good.

She tells U.K. talk show host Graham Norton, "It's going to be the finale of the whole thing. It's the right time for her to come into her own, to be happy and to succeed."

The final two episodes of the show, which began in 2009, will air in the U.K. in December (14).
