Connor Paolo - Eric van der Woodsen on Gossip Girl - whose hair has been improving weekly ever since he came out of the closet - will not become a regular on the series.
However, fear not, he will still be appearing on the show as a recurring character.
EW's Michael Ausiello reports that Paolo turned down the offer to become a regular because "the contract called for him to appear in only half of this season's 25 episodes, which is about what he's been averaging as a recurring player, anyway. So, basically, by remaining a free agent, he's got the same gig with none of the strings attached."
Makes sense. In my opinion, the character of Eric is meant to remain secondary in the show, anyway.
