Mark Zuckerberg celebrated the 40th birthday of his wife, Priscilla Chan, cosplaying as a pop star. The billionaire, who arrived at the event in a classic tuxedo, stripped down onstage to reveal a sheer blue jumpsuit underneath. The outfit was the same one worn by “Beautiful Things” singer Benson Boone at the 2025 Grammy Awards.
“Your wife only turns 40 once! Shoutout to @bensonboone for the jumpsuit and new single,” Zuckerberg wrote on Instagram, sharing a clip of his performance.
Boone, who released a new single called “Sorry I’m Here for Someone Else” on Friday, used the jumpsuit during his performance at the Grammys. The custom piece was made of a sequined mesh fabric designed by Boone’s stylist Monty Jackson. The jumpsuit features a flared leg, an open front and a silk collar. Zuckerberg also wore the matching blue belt created by Rio Warner for Boone’s performance.

The extravagant party, held on Tuesday, was attended by Chan’s family and friends. The event was also marked by multiple outfit changes, with Chan wearing three different outfits throughout the night. She wore a white ballgown with crystal embellishments, a plunging black dress with a shawl and shiny red dress.
“Turned forty surrounded by family, friends, laughter and dance. I am so so lucky to be so loved,” Chan wrote on her Instagram.
Zuckerberg and Chan started dating in 2003 when they met at a Harvard University fraternity party. The couple married in a surprise ceremony in May 2012. They have three daughters: Maxima, August and Aurelia.
