Rihanna has been updating her fans about the fun she's having during her vacation. Apart from that, she's been treating them with a series of raunchy bikini pictures during her holiday in St. Tropez.

The singer has always been generous to share some candid moment during her recent and past vacations. And Rihanna has done it again by flaunting her physique on Instagram, for all the world to see.

Rihanna posted a picture of herself while pulling up her animal print bikini bottoms which she matched with a zigzag patterned top. In another photo, she was wearing a floral bikini and posed with her friends aboard but appears to be topless.

The "Where Have You Been" singer and her group of girl friends are touring all over Italy in a luxury yacht. Yesterday, Rihanna invited former basketball star Magic Johnson to join the festivities. The 52-year-old basketball legend hopped in the yacht when it moored off the coast of St. Tropez, south of France.

Rihanna and Magic greeted each other with a hug before she showed him the rest of the yacht. Magic took it to his Twitter account saying, "We had a great time hanging with @Rihanna & her friends on her yacht."

At one point, the singer was seen chatting a photographer who rescued her friend when she fell off a jetski. It was certainly obvious that Riri was enjoying herself as she was seen laughing all throughout the day. Perhaps taking a break from all the turmoil that has happened to her during the past weeks.
