When a straight dad gets blasted by the Internet for being an attentive father, what chance do two loving gay dads have?

On this week's episode of 'Gossip Girl,' called 'Blair Waldorf Must Pie,' B's father—whom, you'll recall, ran off with a male model—reveals his identity at last. He'll be played by John Shea, best known as Lex Luthor from 'Lois & Clark: The New Adventures of Superman.' At nearly 60, he will also be the only parent on this show old enough to look like he could have sired a teenager post-being one.
