Ri-Ri is a pro when it comes to provocative.
Rihanna is still a good girl gone bad — she’s pictured rolling a blunt stuffed full of diamonds on the cover of her new single.

The singer – who often sports the marijuana symbol on her clothing – will release the new song to radio stations worldwide on September 26 at 8am ET. The aptly titled Diamonds will be available to buy on iTunes an hour later.

Are there any details about her highly anticipated new album?

The CD is set for release in November, and Rihanna launched a teaser website Rihanna7.com dedicated to it.

While the name of the album has not yet been released, according to directlyrics.com, it may be called 7 World Wonders.

The website claims Rihanna’s music label, Univeral Music, has bought  a number of domain names – including rihannah7worldwonders.com and rih7worldwonders.com – containing the alleged album name.

The singer is also set to kick off her Diamonds World Tour on March 8, 2013 at the Niagara Center in Buffalo, New York.
