The 1920's fashion is back -- at least for Kris Jenner's birthday bash. In celebration of her 60th birthday, her children threw her an extravagant Gatsby-themed party. The mother of six celebrated with fashion and style wearing a blast-from-the-past attire. The Great Gatsby-themed bash was held in West Hollywood with tons of celebrity guests.

A source tells Us Weekly, the black-tie event kicked off with a cocktail hour where Jenner and boyfriend Corey Gamble greeted guests, including John Legend, Chrissy Teigen, Tommy Hillfiger, Balmain designer Olivier Rousteing, and longtime family friend Ryan Seacrest. Also in attendance were Will and Jada Smith, Harry Hamlin, Lisa Rina, Jonathan Cheban, Kyle Richards, as well as Kathy and Rick Hilton.

But let's not forget the most import people in Momma Kris' life, her daughters Kim, Khloe, Kourtney, Kendall, and Kylie were all in attendance, and made a video that they screened during the fancy event.

Reports say that the sentimental clip included all the girls in a recording studio singing an original song they wrote -- with the help of Kim's husband Kanye West, called "You Love Your Friends." A side note, the video was a parody of a 1985 video called "I Love My Friends" that went viral on YouTube. "It was very funny and campy and had funny lyrics about how much Kris loves her friends," the Us Weekly source said. "The girls would sing the verses and in between each verse it would cut to a video of someone from one of Kris's favorite places or people singing, 'You love your friends."

But the last scene was perhaps the biggest surprise, where Kris' ex Caitlyn Jenner in a hot tub giving a birthday toast, and saying that she couldn't make it.

Additionally, the source said that everyone enjoyed the party, dancing and having drinks. The celebration lasted until around 3 a.m.
