The Blast obtained a copy of the traffic citation from the Florida Highway Patrol, stating Williams was clocked going 86 MPH in a 65 MPH zone Saturday morning.
Documents from the citation state she'll pay a $281 fine.
According to the Blast, the citation states she was not traveling with her new baby daughter Alexis.
It's unclear why the new mom was in a rush, but The Blast notes she did attend a charity event in Washington D.C. later that day.
Williams married Reddit mogul Alexis Ohanian last month in New Orleans.
