Rihanna back with Chris Brown

"When you add up the pieces from the outside, it's not the cutest puzzle in the world," Rihanna admitted to Rolling Stone, which hits newsstands this week with her gracing the cover above the headline, "Rihanna Crazy In Love".

"You see us walking somewhere ... and you think you know. But it's different now. We don't have those types of arguments anymore. We talk," she said. "We value each other."

But she noted that Brown is on probation with her as well, saying, "He doesn't have the luxury of (messing) up again."

"That's just not an option ... And I wouldn't have gone this far if I ever thought that was a possibility."

The interview was published three days after Brown's latest dustup, which involved fellow musician Frank Ocean, over a parking space at a West Hollywood recording studio. Ocean has said he wants Brown prosecuted following the Sunday brawl.

In 2012 Rihanna was rated by Time and Forbes magazines as among the world's and celebrity arena's most powerful people.
