According to a recent Vogue article about the LA Dance Project, Rob admitted that Natalie Portman invited him to the event because they live near each other & did it as a neighborly gesture.
Like any great dancer, Benjamin Millepied knows how to make an entrance. For the world premiere of his new collaborative, L.A. Dance Project, at the Walt Disney Concert Hall Saturday night, the former New York City Ballet principal choreographed a lavish evening (together with cohost Van Cleef & Arpels) complete with an intimate VIP dinner, a boisterous after-party, and even a Robert Pattinson sighting. “I live near Natalie [Portman] and she invited me to come,” said the Twilight star, who chatted with fellow guests Dita Von Teese and Jaime King and gamely posed for fan photos.
