Ted's getting a new love interest on 'How I Met Your Mother' in the form of 'House' veteran Jennifer Morrison, The Ausiello Files reports.

Morrison will play Zooey, "the biggest female character we've maybe ever added to the show in Ted's life," executive producer Craig Thomas told EW.com. So, uh, is she the mother?

We don't really know. All Thomas would say is that "This is a big arc -- a huge arc. It's going to be a little less date-of-the-week for Ted, which season 5 was."

According to Ausiello, Zooey and Ted's relationship will be an opposites attract situation. Zooey wants to save an old New York hotel from being demolished so a fancy new bank tower can take its place, and Ted's the one designing said tower. Drama!

The exact length of Morrison's stay on 'HIMYM' is unknown. Deadline Hollywood reports that it could be as few as five but as many as 13 episodes.
