Rihanna has won GRAMMYs and sold out arenas, but when she stepped into the booth to record for DreamWorks' animated film Home, she didn't know what to expect.
In a sit-down with ET's Kevin Frazier, the "FourFiveSeconds" singer admitted that she was nervous recording voice-overs for the movie, out March 27.
"You don't want to just get the job because you're famous," Rihanna said. "[I want to do] something that Dreamworks can really stand behind and not something that they will say, 'Ok, we should have thought this over.'"
The movie follows Oh (voiced by Jim Parsons), a loveable extraterrestrial who lands on Earth and finds himself on the run from his own people. On his journey, Oh forms a friendship with an adventurous girl named Tip (voiced by Rihanna). The movie also features the voices of Steve Martin and Jennifer Lopez.
Rihanna may have felt the pressure in front of comedy stars Parsons and Martin, but she outshines them when it comes to music with eight GRAMMY wins.
Martin falls just short with five GRAMMYS (three for music and two for comedy), while Parsons hasn't been honored with a nomination.
"I'm with music royalty!" The Big Bang Theory star said.
A more recent honor for Rihanna was being named the first black woman to front a campaign for Dior.
"It doesn't feel real," Rihanna said. "It seems impossible almost."
Rihanna joins a list of Dior spokeswomen that includes Jennifer Lawrence, Charlize Theron, Natalie Portman and Marion Cotillard.
