"How I Met Your Mother" will be back for a ninth and final season that will reveal — finally — who the mother is.

CBS and 20th Century Fox Television announced Wednesday that the series would be back for one final go-round with series regulars Josh Radnor, Jason Segel, Cobie Smulders, Neil Patrick Harris and Alyson Hannigan, as well as series creators Carter Bays and Craig Thomas.

For eight years, viewers have wondered about the identity of the titular mother — and she will finally be revealed in the final season.

"Through eight years, 'How I Met Your Mother' has mastered the art of leading-edge comedy, emotional water-cooler moments and pop culture catch phrases,” said Nina Tassler, president of CBS Entertainment. “We are excited for Carter, Craig, Pam Fryman and this amazing cast to tell the final chapter and reveal television’s most mysterious mother to some of TV’s most passionate fans.”
