Something more than those scantilly clad bikini pics have come out of Rihanna's trip to Barbados.  Thanks to the "Diamonds" chick flashing her perfectly perky T&A in a fully open balcony window (where she knew paparazzi had been watching her for days).

And she's staying mum about her newest doozy....

While Rihanna rocked swimsuits that got smaller and smaller each day that she was back on her native island of Barbados recently, she was caught (shocker) fully naked on her balcony.

Pics just leaked of Rihanna changing from a black bikini to a little red one.  And the paparazzi camera caught her fully naked bod as her ass was propped up on full display in the open door.

Despite the nude pics hitting the net last night, the "Fresh Off The Runway" singer has yet to say anything about it.  Cat never got her tongue before when she put out her own damn near naked pics or when she was trying to clear up a rumor.  But this time, she remains mum.

Is that because she knew the pics were being taken...seeing that she keeps turning around looking out the balcony window while chillin' butt ass naked? Just a thought...

All you freaks can peep the pics HERE, because we can't post them here.
