The evening – presented by bebe – kicked off with a private dinner at The Wine Gallery and then continued with a rooftop after party under the stars.
Young Hollywood was on hand to wish the Pretty Little Liars star well. Guests included Teen Wolf's Colton Haynes, Hale's PLL costar Tyler Blackburn, The Big Bang Theory's Johnny Galecki and Glee's Nolan Gerard Funk.
Haynes Tweeted his congrats early Saturday morning. "Huge Congrats to @lucyhale on her Nylon cover. Was a fun night at the dinner," he wrote.
At the holiday-themed party, guests sipped cocktails from SVEDKA vodka while hanging ornaments on a Christmas tree, wearing Santa hats and posing for snapshots in a photo booth.
