Fergie -- 2 Ass 2 Furious

Fergie got cheeky in south Brazil yesterday with husband Josh Duhamel -- the same day Paul Walker, Vin Diesel, Ludacris, Tyrese and the rest of the "Fast and the Furious 5" cast hit the beach in Rio.

"Fast Five" is scheduled to begin filming any day now in downtown Rio de Janeiro. But as for Fergie ... we're told the Black Eyed Peas tour just happened to hit Brazil at the same time ... just a few hundred miles south in Florianópolis.
