Cobie Smulders knows the identity of the bride and groom getting hitched on How I Met Your Mother this season, and she’s… unfortunately not squealing. Bummer. She is, however, sharing her thoughts on the top-secret nuptials, which we’ll sneak a peek at in the Sept. 20 season premiere. The actress—whom I caught up with at last night’s 2010 Entertainment Weekly and Women in Film pre-Emmy bash—also previews the next chapter in the Robin Sparkles saga, hinting that the follow-up to “Let’s Go to the Mall” and “Sandcastles in the Sand” will be “loaded with sexual innuendo,” and proposes a new nickname for her Emmy-winning costar Neil Patrick Harris. The video’s after the jump!
