As Riley Keough, Chloë Grace Moretz, Parker Posey, and Hailey Baldwin made their way inside the Highline Summer Party hosted by Coach on Wednesday evening, they had to walk past a bald man sleepwalking in his underwear. It was a jarring juxtaposition with the scantily clad summer crowd, but thankfully the life-size sculpture by artist Tony Matelli never opened its eyes.

Coach designer Stuart Vevers was there as well, having flown straight from London Fashion Week Men's to greet his many celebrity muses, who ate popsicles and clamored for custom flower crowns. It wouldn't have been a proper summer party in New York without talk of far-off places like Mykonos and jet lag amongst the crowd, but Keough and Moretz had summer love on the brain. Moretz said her favorite memories of summer involved "random boyfriends," and Keough — who arrived with her husband — echoed with an emphatic, "Yesssssss!"

"All hot and sweaty," The Girlfriend Experience star continued. "I was thinking about that today... Summer love." Meanwhile, her husband stood calmly outside a ring of photographers, arms folded.

"One of my last boyfriends, we just dated in New York over the summer and it was so nice," said Moretz. "I was, like, 17." She wouldn't say who this brief fling was with, though.

Now, Moretz is, like, 19, and dating 17-year-old Brooklyn Beckham, Victoria Beckham's son. Her date for the evening was her mother, however, as Beckham was back in Los Angeles. Here's hoping that one lasts longer than a summer!
