Rihanna is back to her old self as she swaps her reserved maxi dress for another raunchy bikini photo.
The singer shocked paparazzi at the weekend as she donned a long, blue printed maxi dress for dinner in the wealthy Monaco.
The dress was a light, one-shouldered chiffon maxi dress and was possibly the longest hem Rihanna has worn during her career. The x-rated star was sure to harden the edges of her feminine look though, wearing a Medusa-style gold snake band around her upper arm and walking with a cigarette casually slung in between her lips.
