Girls Gone Wild Founder Joe Francis was socked in the head by a disgruntled BF in Miami on Saturday night.

J.F, who’d been sipping Bacardi mojitos at M.I.A’s Club Cameo, was in the company of socialites Anna Anisimova and Tinsley Mortimer but paying more attention to a group of Brazilian models. The boyfriend of one of the South American sirens took offense and initiated the violence, a says a snitch.

After the assault, an embarassed Francis was escorted from the scene by security.
