The former Days of Our Lives star (and Abercrombie and Fitch model) will be a "heavily recurring" character on the show's second season, starting with an episode fairly early on. The character is described as a JFK Jr. type, as Entertainment Weekly puts it:
Gorgeous, smart, athletic, charming, and naturally confident, Teddy has the unique ability to make any girl feel like she’s the most beautiful person in the room. And any guy like he’s a cross between Shrek and Jiminy Glick.
Gotta admit, he's not tough to look at. But is it enough to make you say "Ethan who?" And does 90210 need more than just a hot guy infusion to make you tune in?
