Rihanna: 'I could turn a straight woman bi'

has again sparked controversy after posting a message on Twitter claiming that she can turn a straight woman bisexual.
The pop star made headlines last week after uploading pictures of herself throwing money at female strippers.
She has now posted on Twitter
: "Guarantee to turn a square into a Bi bitch!!!"
The post is a reference to E-40 song 'Function', which contains the lyric "Guarantee turn a square to a bop bitch".
Rihanna reportedly angered Saturday Night Live
producers by missing the show's dress rehearsal before her performance on the May 5 episode.
In April she caused concern by posting pictures on Twitter showing her sitting on the shoulders of her bodyguard, who appeared to have white powder
on his head.Photo gallery: Good Girl Gone Bad - Rihanna's career in pictures
