Rihanna is set to join Season 9 of "The Voice" as an adviser to all four of the show's judges.

E! News reports judges Gwen Stefani, Pharrell Williams, Adam Levine and Blake Shelton will all have the "Diamonds" singer at their disposal in molding their recruits into the artists they would have them be.

"We landed Rihanna to be the key adviser to all the coaches this fall," said NBC Entertainment Chairman Robert Greenblatt told reporters. "This is one of music's true supervisors coming on board to influence the lives and careers of the performers."

Given all the rumored sizzle in her love life of late, Rihanna may have to make time in her busy schedule for the new gig. Reports are she and Formula One race car driver Lewis Hamilton are growing closer.

"Rihanna and Lewis had a nice little getaway last weekend in Barbados," said a source. "Rihanna also spent time with her friends and family but Lewis was the only romantic interest on her mind. They had lots of fun together around the island and also got some private romantic time."

Until recently, Rihanna had been linked to Real Madrid soccer star Karim Benzema. Now, that seems like ancient history.

"Karim is fading out and it looks like Rihanna has only one guy on her mind, and that's Lewis," a source added. "She is taking it very slow and just having fun, but she likes who he is and what he is about." There's "no label on them just yet."

As for "The Voice," Levine and Shelton have been with the show since it began in 2011. Season 9 will be Williams' third season, after he joined the show with Stefani in season 7.

The new season is set to premiere on NBC in September.
