Rihanna Whitney HoustonWithout exactly being asked, Rihanna has clarified that she isn't interested in filling Whitney Houston's shoes in an upcoming remake of the 'The Bodyguard.'

Rihanna tells OK! magazine she won't take on the role of singer Rachel Marron, played by Houston in the 1992 hit film, because it wouldn't be challenging enough for her. Rihanna says that she would like to escape into a role rather than play a singer.

"Absolutely not," Rihanna says. "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."
