To surprise his wife, Priscilla Chan, on her birthday, Mark Zuckerberg traded his usual billionaire CEO attire for a surprising and flashy outfit to make a statement at the party. The Meta chief showed up wearing a sparkling blue jumpsuit — a look inspired by singer Benson Boone's last month's Grammys performance.

Zuckerberg's unexpected fashion moment unfolded at Priscilla's 40th birthday party, leaving the guests amused and his wife bursting into laughter.

Sharing a video of his performance, Zuckerberg wrote on Instagram, "Your wife only turns 40 once! Shoutout to @bensonboone for the jumpsuit and new single."

Sharing some glimpses of her special day on social media, Priscilla wrote on Instagram, "Turned forty surrounded by family, friends, laughter and dance. I am so so lucky to be so loved."
