If it were up to singer Leona Lewis, the highly anticipated Fifty Shades of Grey movie would have some very musical stars! With rumors flying around Hollywood of who will be cast in the upcoming Fifty Shades flick, Leona weighed in on who she thinks should star as Anastasia Steele and her BDSM lover Christian Grey. "For Christian Grey it has to be someone really hot and super smooth,” Leona admitted in a recent interview to MTV News. “Why am I just thinking of Chris Brown? Maybe Chris Brown!" So who does the 27-year-old singer think should star opposite Breezy as his innocent-submissive-turned-wife? Taylor Swift, obviously. Dakota Fanning and Elizabeth Olsen were also thrown into the mix as potential Ana’s, but Leona was definitely more in favor of Chris playing Christian, despite the singer’s past criminal record. Universal Pictures and Focus Features purchased the rights to author E.L. James’ best seller earlier this year, and screenwriter Kelly Marcel has been chosen to pen the adaptation for the big screen. We’ll wait anxiously to hear who will be cast for the Fifty Shades of Grey movie, though it’s probably safe to say Leona’s suggestions will probably stay just that — suggestions.
