Rihanna Set To Premiere 'Only Girl (In The World)'

New single, produced by Stargate, will premiere Tuesday on RyanSeacrest.com.

Rihanna may be in the midst of filming "Battleship," her Hollywood debut, but that doesn't mean that the pop star won't be focusing on her music. Just less than a year after the release of her last album, Rated R, the singer is already set to debut a new single called "Only Girl (In the World)" from her fifth studio album.

The song, which was produced by Stargate, will premiere on Tuesday (September 7) on RyanSeacrest.com at 3 a.m. PT/6 a.m. ET. This isn't the first time the Barbadian songstress has worked with the Norwegian producing team. She has collaborated with the duo on earlier hits including "Please Don't Stop the Music," "Hate That I Love You" and, most recently, "Rude Boy."

Just days after joining Twitter, the singer hinted at the single in a tweet directed at Seacrest. "@RyanSeacrest Soon! In less than 10 dayz ima send u sumn special, and ur gonna play it OVER and OVER, like I'm the only girl in the world!" she said.

In addition to Stargate, the singer has also been working with Sean Garrett. Back in June, the producer spoke to MTV News about the new album, which he said is going to be more uplifting than the darker material on Rated R. "I can definitely say that her album is definitely gonna be way more exciting, happy," Garrett told MTV News. "I hope she doesn't mind me saying this. I love Rihanna. She's fun, she's like a sister, and I tend to think she doesn't really take herself too seriously. And I think that's what this album is gonna be about."

While not much else is known about the project, Rihanna has also reportedly recorded a song called "Cheers," with production by the Runners.
