Rihanna and her slim & trim bod were on full display yesterday as she carried on with her Holiday vacay back home in Barbados.  Check out pics of the pop diva chillin' in a sexy teal monokini in her $9,000/night private villa.  Then she hits the streets for a little "cheap & cheerful" shopping...


With her iPhone and a box of smokes in tow, sexy Rih Rih was spotted taking in vacay in the most fabulous way possible.  She's back on her native island of Barbados, and nothing's too fancy for the Ambassador of Tourism Ms. Fenty.

The "Diamonds" singer and her friends are holed up in a $9K/night private mansion-villa, The Cove Spring House, that's big enough for 20 people.  It's laced with 10 bedrooms, hand-picked Ralph Lauren furnishings, outdoor living spaces and expansive verandahs.


And when she needed a break from soaking up the sun (and weed) in her uber plush palace, chick grabbed her Chanel bag and went shopping at the local markets in Bridgetown.




She threw on jeans and a white tee with her gold capped Louboutins to shop it up at local jewelry stores.  She also revealed recently she still has to cop her youngest brother Rajad a Christmas present.  And since he's 16 nw, he's outgrown all the toys she used to cop him as presents.


And after she and bestie Melissa shopped it up, Rih grabbed a kiss from her mom.



Later on in the day, Rihanna hopped in her own Jeep and drove to a nearby drive thru for some lunch.  Gotta love it.
