As we were walking into Zac Posen on Sunday night — the show was held on the second-floor balcony of Avery Fisher Hall, overlooking the fountain — we noticed quite a commotion happening in the courtyard below. Everyone peered over the railing to see a tall blond woman, her curls blowing in the wind almost as dramatically as her diaphanous black lace skirt. She stood on the ledge ringing the fountain, her arm slung around a man, and posed for a scrum of what was easily 50 photographers. Oh God, we thought. It’s Lohan: The Return.
