The O.C. grad will recur as Will, a new neighbor who befriends Scarlett and her hunky roommate. (And while there’s no confirmation that Carmack’s neighborino will be a threat to Gunnar and Scarlett’s burgeoning attraction/musical partnership, come on. We’ve seen those abs. We’ve got a good idea of how this song ends.)

Carmack played rich jock Luke on two seasons of Fox’s teen soap. His other TV credits include Related, Desperate Housewives, NCIS and CSI: NY.
