We doubt Anderson Cooper spends much time at Eastern Bloc — the New York City gay bar owned by boyfriend Benjamin Maisani — but even around the holidays? When nightlife personality Mike Diamond stopped by the bar’s Hanukkah Hairy party (or was that Hairy Hanukkah?), neither Cooper nor Maisani could be seen among the crowd. It’s as if they don’t want to be spotted in public together. Or with Jews.
