Mark Zuckerberg and Priscilla Chan have been together since college in the early 2000s. A lot has changed since then, including their style.

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.
