Kylie Jenner and boyfriend Tyga attended Kris Jenner‘s dazzling, Great Gatsby-themed 60th birthday on Friday in style.

Jenner, 18, with her short new ‘do sleeked back, arrived to the event in a sparkling gown by designer Yousef Al-Jasmi, while Tyga, 25, dressed in a dashing white suit jacket, accessorized with black lapels, black bowtie and black pocket square.

“BlackBird ridin w the Dillinger,” he captioned a photo of them together from the party, in The Lot Studios in West Hollywood, California.

Jenner shared scenes from the party with her Snapchat followers, including a peek at the makeup process beforehand.

Of course they weren’t the only ones from the Kardashian-Jenner clan embracing the theme (which had been planned for months, a source previously told PEOPLE).

Jenner’s older sister Kourtney Kardashian channeled Jay Gatsby in a gender-bent spin on the titular tycoon and Kendall Jenner went into full flapper mode as Daisy Buchanan. (Complete with blond wig.)

The guest list Friday also included Kanye West, Chrissy Teigen and John Legend, Boy George, Melanie Griffith, Olivier Rousteing, Lisa Rinna and Corey Gamble.

It’s been a busy week of birthdays for the Keeping Up with the Kardashians stars, with Kendall turning 20 on Tuesday.

Though Jenner and Tyga went public with their relationship earlier this year, she told Elle Canada that she probably won’t “ever be super-public about my relationships.”

“I do think that if you let people in too deep, it gets hard – your fans get too invested, and then they know when you break up and make up,” she told the magazine in its December cover story. “I don’t want people to know every time we fight or break up, so I’d rather keep some things private.”
