The 22-year-old singer said that she has no interest in following in Whitney Houston's footsteps because she does not want to play the part of a singer.
The S&M star, who is set to star in Battleship, told OK! magazine, 'I want to separate the two. I hate it when singers do singing movies all the time because you can never look at them as anybody else.
'I want to play a character. My whole life is playing Rihanna, being a singer won't be a stretch for me.
'I like challenges and being an actor is playing a role, being able to step into somebody else's shoes, that's the excitement.'
