Sexiest Rihanna Video Yet? 'Pour It Up' Singer Shows Off Thong And Bedazzled Bra [PHOTOS]

"Pour it Up" may be Rihanna’s raciest video yet. The 25-year-old showed off behind-the-scenes photos from the shoot, which includes Rihanna wearing a bedazzled barely-there bra, “stripper heels” imprinted with dollar signs, and a red thong.

In some photographs, she appears sitting on a golden throne, which makes sense as she recently broke Billboard records by having 10 No. 1 pop songs. She's the first singer in the 20 years that Billboard has had charts to accomplish such a feat.

Showing off her long legs and stunning body, Rihanna exudes sex appeal in her latest video, which is about strips clubs, drinking and partying. In one photo, Rihanna is shown lying on the floor surrounded by dollar bills.

The Barbadian beauty, who's known for frequently changing hairstyles, shows off a new hairdo and makeup, with white pin-up curls and purple eyebrows. Previously, she has had every color from red to black and every style from super long to a pixie cut, but this look may be the most shocking of all.

Meanwhile, Rihanna has a lot to celebrate these days. She has a new fall collection with MAC, which features powder plush, brow liner, lipsticks, and lipliners. The collection, which is available online and in MAC flagship stores, will be at other locations from Oct. 3-31.
