(CNN) -- A day after his social media company went public, Facebook co-founder and chief executive Mark Zuckerberg married his longtime girlfriend Priscilla Chan on Saturday.
The news was announced where else but on Facebook.
"Mark added a life event to May 19, 2012 on his timeline: Married Priscilla Chan," the page's activity feed said.
Zuckerberg, 28, posted a simple wedding photograph, showing the couple against a backdrop of plants and small lights on a string.
Both he and Chan also updated their relationship status to "married."
