Peter Bacanovic, just one week out of home confinement, hit the New York City Ballet benefit gala last Tuesday night. Martha Stewart’s former broker looks youthful for 43, if a little weary. “This is my first time out,” he said. “I’ve been under water for three and a half years. I’m so glad to be here. Isn’t this great?” Bacanovic came with socialite Fe Fendi, his good friend and a fellow balletomane. Fendi said Bacanovic would have preferred a different company—“He’s an ABT man.” But the City Ballet opening was perfectly timed. “I said, ‘Let’s celebrate. Let’s go get drunk,’ ” said Fendi. “We’ll try.” Bacanovic said he receives Stewart updates through mutual friends: “I don’t know if you’re aware of the law, but we’re not allowed to communicate.” Couldn’t he watch her TV shows? “I don’t watch TV. I never have,” he said. The next day, he left for the Caribbean. Friends say he’s considering a move to the West Coast to work in film.
