Hollywood was ecstatic over the passage of same-sex unions in the Empire State. Twitter blew up with tweets of celebration from folks like Ellen DeGeneres, Ricky Martin, Lady Gaga, Lance Bass, Alec Baldwin, Darren Criss and Kathy Griffin, among others. But it was Neil Patrick Harris and E!'s own David Burtka who marked the milestone by announcing their engagement. "David and I did propose to each other, but over five years ago!" Harris tweeted. "We've been wearing engagement rings for ages, waiting for an available date."
