A law firm has let slip that Facebook paid $65 million to settle a suit charging that founder Mark Zuckerberg swiped the idea for the website from former college roommates.

Quinn Emanuel Urquhart Oliver & Hedges law firm boasted in a January advertising brochure about outcomes of an array of cases it handled last year, among them a $65-million settlement from Facebook.

The Recorder, a California legal publication popular among lawyers and judges, on Wednesday published a story about the leak.
