Leo DiCaprio was an unexpected guest at a model-packed bash for women’s retailer Bebe at Meatpacking District club Provocateur on Wednesday night. At his most comfortable in a room full of models — who included Nina Agdal, Coco Rocha and Selita Ebanks — Leo and a group of friends arrived at 11:30 p.m., when the movie star did his best to go incognito in a newsboy cap, cardigan and gold necklace. A witness said, “Leo chose to sit at a table directly across from Nina’s table. He sat high on a banquette, to scope out the scene. He texted on his phone and smoked electric cigarettes.” But the spy added, “He didn’t chat up the girls at all . . . he sat with his boys and a mystery blonde, who looked a little like his most recent girlfriend, Toni Garrn.” Other guests at the bash included actress Katrina Bowden and Universal Republic’s Charlie Walk. Earlier in the night, Leo had been spotted dining in private at Michael’s with his talent agent Rick Yorn and Martin Scorsese. We’re told they were in “an intense discussion about a blockbuster project.”
