Wearing a sleek Dolce & Gabbana suit, a button-down and his famously touseled hair, Pattinson worked the red carpet at the Landmark Sunshine Theater as dozens of cameras flashed and fans broke down into tears. "Robert completes me!" exclaimed one 11-year-old fan.
Pattinson – who plays sexy vampire Edward Cullen to Stewart's soulful teenager Bella Swan – arrived at the screening about 20 minutes before his rumored real-life love Stewart made her appearance on the red carpet.
After Pattinson went into the theater, Stewart (dressed in Valentino) arrived and posed for pictures with costar Nikki Reed – then skipped the screening altogether.
And while Pattinson and Stewart avoided a red carpet run-in, their New Moon costars artfully dodged questions about the pair's rumored romance.
"Whatever their lives are people should let them have their privacy," said Peter Facinelli, who plays the Cullen family patriarch in the Twilight series.
Meanwhile Kellan Lutz, who plays Pattinson's onscreen brother Emmett, played up the dumb blonde stereotype. When asked about his costars' relationship, Lutz, who recently dyed his hair, joked, "I'm a blond. I don't think about anything!"
Later in the night, Pattinson and Stewart both partied at AVENUE lounge where they were escorted to a corner table on the mezzanine and were seen talking and laughing.
