Rihanna knows how to grab eyeballs and remain in news. After the advent of social media, this 27-year-old Barbados beauty leaves no opportunity to click her selfie (self-portrait from her smartphone) and post it online.

The "Queen of Selfies" does it the best and often delights her fans by posing semi-naked pictures of herself on Instagram. The "Diamonds" hit maker does best with skimpy bikini shots, butt-barring pictures of self in minute thongs or the one where she points her hand to her front with a provocative caption "I prefer my pu$y in pink ."

Guess what is her Instagram's profile picture? It's a collage of the 25-year-old singer with her three pictures pointing to her bikini area and the caption of the picture is equally racy - "PU$Y x MONEY x W££D #RihPost."

The "We Found Love" star is not new controversy and considers pop queen Madonna as her idol and biggest influence. Back in 2011, she told revealed to Digital Spy that she wants to be the "black Madonna".

"I think that Madonna was a great inspiration for me, especially on my earlier work. If I had to examine her evolution through time, I think she reinvented her clothing style and music with success every single time. And at the same time remained a real force in entertainment in the whole world," the singer said.

In April 2012, the singer stunned fans by posting a picture of herself 'cutting up' a white powered substance on the top of a man's head on Instagram from her time at American music festival Coachella.

RiRi, who is also heavily influenced by the Jamaican singer-songwriter Bob Marley, is seen smoking weed in her selfies. The singer has told Rolling stone magazine in 2010, that Marley is "one of my favorite artists of all time [...] he really paved the way for every other artist out of the Caribbean."

This "Umbrella" star pulls off a provocative pose like no other and is very open to show her breasts and other body parts! Take a look at some of her sexiest, raunchiest snaps to date.
