Jennifer Morrison is back on the lot where she spent more than five seasons as House's Dr. Cameron — but this time she's in a new role that showcases a killer comedic side we never knew she had. Jennifer joins CBS' How I Met Your Mother on October 18 as Ted's new love interest, a mischievous architecture nerd named Zoey Van Smoot — the most likely candidate yet to be the titular mom. 

"Without giving anything away, it's a very, very big character who influences Ted's life quite a bit, so we were being very picky with who we cast," reveals creator Craig Thomas. "We'll see Zoey become a fixture of this group's world."
