Rihanna seems to be enjoying going down - under. The "S&M" singer was spotted in Australia on Thursday doing a little shopping at The Tool Shed, a popular sex shop in the heart of Sydney's gay district.

Moments before Rihanna emerged from the store with a devious grin on her face, a male assistant was spotted leaving with two black bags full of purchases.

Rihanna kept quiet about the contents of the bags but gave a smile as she left the huge store that sells everything from two-foot dildos to poles for pole dancing; the shop also carries S&M gear which seems rather appropriate.

A spokesman for the shop later said that the visit was arranged earlier in the day and they had to ensure no-one else was in the store during her visit. "I can't say what she did or what she bought, it's top secret," he added.

Rihanna's visit has fueled speculation that she will put in an appearance at the city's hugely popular gay and lesbian Mardi Gras festival.

Rihanna is currently in Australia on tour.
