Rihanna & Ke$ha Like To Go Down...(PHOTOS)

A red hot Rihanna was spotted arriving in Adelaide, Australia yesterday. She was busy working out the logistics for her "Last Girl On Earth" tour.

Rihanna strolled through the Adelaide airport cool as a cucumber in a black sweatsuit. The always glammed up RiRi was extremely casual as she rocked a fitted black cap and athletic sneakers. Rihanna also addressed the rumors about her involvement in the remake of "The Bodyguard," which she said are not true.

While Rihanna was red hot in Australia, party girl singer Ke$ha was busy hiding from the paparazzi when she arrived in Sydney, Australia. Ke$ha was an audience member at Rihanna's concert in Sydeney, where spectators say she was playing tonsil hockey with British DJ Calvin Harris. When asked by the paparazzi if she and Calvin were an item, she simply kept mum.
