TYRA Banks is laying off the sauce. The talk show host was at dinner at Pranna in Murray Hill with boyfriend Johnny Utendahl when the manager sent over a couple of glasses of complimentary champagne. A diner at a neighboring table tells Page Six, “She was grateful but ended up not drinking. She doesn’t booze anymore. I guess that’s how she ended up dropping 30 pounds.” Banks had a guest spot with Hilary Duff on Monday’s episode of “Gossip Girl.”
