What do you get when you combine Taylor Swift, Beyonce, Jay Z, Justin Timberlake, a handful of models, pop stars and a poop-emoji mask? Apparently, you get Swift's 25th birthday party, which was anything other than what that mask might suggest.

The crossover "Blank Space" singer celebrated the quarter-century milestone on Saturday at her New York City apartment with a surplus of award-winning musicians, many of whom had appeared at Z100's  2014 iHeartRadio Jingle Ball earlier that day, E! News reported.

Also on the guest list were her gal pals, singer Selena Gomez, Jaime King of "Hart of Dixie" and models Karlie Kloss and Chrissy Teigen. Rapper Iggy Azalea, singer Nick Jonas and his girlfriend Olivia Culpo, "Stay With Me" singer Sam Smith, "The Fault in Our Stars" actor Ansel Elgort, singer Charlie XCX, Shawn Mendes, the band 5 Seconds of Summer and the sisters from the group Haim also joined the roster, the site said.

"So this is being 25..... #WHAT #bestbirthdayEVER," Swift wrote around 2:30 a.m. on Sunday, sharing a picture of herself flanked by her pals -- including Timberlake wearing the aforementioned mask. Swift sported a Santa hat, Beyonce struck a pose in flared sunglasses, and everyone else looked beyond cool.

Then the Instagram photos, tweets and messages from her and her famous guests flooded social media. (Obviously! See below.)

"I just want to thank anyone who wished me happiness today. You're my friend. These are my friends. And I'm so lucky," the "Blank Space" singer wrote, posting pics with her girls on Twitter.

The revelers danced the night away with all sorts of funky props, and pizza-delivery guys were reportedly spotted in the middle of the night dropping off 40 pies. Personal security guards ran a tight ship at the building, E! reported.

The darling of the music industry, who is already having a banner year, was elated with the festivities and wrote lyric-ready messages to share all her feels.

"When you're making a wish, but you already have all you really need standing around you," she wrote, posting a photo of friends surrounding her as she blew out her candles.

Something tells us she doesn't have too much more to wish for. Not even a new boyfriend.

Happy Birthday @taylorswift that was so fun last night! @oliviaculpo
