Long Island divorce lawyer Dominic Barbara is heading up the aisle for the fourth time. Barbara, who’s looking forward to returning to work following an 18-month suspension for professional misconduct, tells us he is engaged to brunette beauty Pamela Gorin, 37. He popped the question outside the polar bear enclosure at Central Park Zoo. Barbara told us, “We actually met many years ago at Nello’s, but we didn’t start dating until three months ago. I couldn’t be happier. I asked her to marry me at the zoo, then we went back to Nello’s to celebrate.” He said they plan to wed in December in Europe.
