Is Rachel Bilson The One We’ve Been Waiting For On “How I Met Your Mother?”

We’ve waited patiently (SO PATIENTLY) for four years to find out who will be the titular mother on our fave sitcom, “How I Met Your Mother.” According to Michael Ausiello of Entertainment Weekly, the show’s executive producer told him that episode #100 of the show would contain “some serious mother action.” He elaborated, “It’ll be the closest Ted’s ever come to her. He’s getting a step closer every episode this season, and episode 100 we kind of go bananas with it.” And guess who Ausiello has just discovered has been cast for a role in episode 100? The amazing Rachel Bilson. I’m jumping up and down because that’s so freaking adorable. [EW]
