IT's official "How I Met Your Mother" will be back for a ninth and final season! I have the details right here.

First thing the five major actors will return. Neil Patrick Harris, Cobie Smulders, Jason Segel, Josh Radnor and Alyson Hannigan are all on board. Here's the big deal though there is a guarantee we will finally meet the woman with the yellow umbrella. Ted's mystery love WILL be revealed in season 9!
