I've got to say, Rihanna is not my favourite, yet through her own faults and probably the things i don't like about her, she'll be a great Whitney...especially through the phase of her life where she was the lowest, Rihanna's current style completely reflects that.
I'd also be keen for a more musical version with Jennifer Hudson, or possibly a version with Jordin Sparks, who could play her during her early years. Maybe it would be a great idea to have a few different women, as a fitting tribute.
Of course, these are all speculations...what i'd really like to know is;
Should Rihanna Play Whitney? Comment below.
