Rihanna is apparently on a rapid-fire fast track to release as many albums as she can in the shortest period of time possible. The singer has just announced that her sixth studio album is due out this fall.

Thursday (Sept. 15), the superstar took to her Twitter page to make the big announcement, in a response to one of her followers. The fan asked, "When's the next album due?" "THIS FALL!!!!!" RiRi revealed with obvious excitement.

Rihanna's camp has reportedly confirmed that the new album is indeed on its way. The 2011 release of Rihanna's sixth studio effort means the prolific pop star will have put out an album every single year from 2005 to the present, with the exception of 2008.

From her 'Music of the Sun' debut in 2005, to 2010's 'Loud,' Rihanna's albums -- including her two remix efforts -- have sold 7.3 million copies in the US collectively.

She's five for five when it comes to charting albums in the top 10, and can boast a whopping 10 Hot 100 No. 1 singles. But, can Rihanna grab her first-ever No. 1 album on the Billboard 200 chart with the forthcoming record? The closest she's come thus far was when her 2007 third studio album, 'Good Girl Gone Bad,' which debuted and peaked at No. 2.
