Arrow finds another Gossip Girl

Looks like the CW's Arrow has set its sights on another Gossip Girl.

 Deadline is reporting that former Gossip Girl troublemaker Willa Holland will be joining the show. She's playing Thea Queen, the boundary-testing celebutante sister of the Green Arrow's sexy alter ego Oliver Queen.

As reported earlier, Stephen Amell steps into the role of millionaire Oliver Queen, who secretly moonlights as Jason Bourne a bow and arrow welding vigilante, with a penchant for green, out to stop crime. Katie Cassidy will be Laurel, a young legal clinic attorney with past romantic ties to Oliver, and possibly Black Canary. Susanna Thompson has been cast as Oliver's mother Moira Queen. Now all we need is a super sexy baddie to round out the overly pretty cast.
