Los Angeles - Rihanna has unfollowed ex-boyfriend Chris Brown on Twitter.
The pop superstar - who was rushed to hospital suffering with "exhaustion and dehydration" on Tuesday night - has deleted the RnB star from her social networking account after speculation emerged that a seemingly offensive song he released on Wednesday is aimed at the Bajan beauty.
Chris - who also unfollowed Rihanna on Twitter following her actions - posted a link on the social networking site to his freestyle version of Kanye West's Way too Cold, formerly known as TheraFlu.
'Feel guilty'
In the song, he raps: "Don't fuck with my old bitches ... like a bad fur ... every industry n*gga done had her," and it continues: "Trick or treat like a pumpkin ... just to smash her."
Following speculation that the song is aimed at Rihanna, Chris tweeted: "Assumptions! I didn't say any names so if u took offense to it then its something you feel guilty about. (sic)".
Rihanna, 24, has attracted a lot of criticism for seeing Chris after he was convicted of assaulting her in February 2009, and the 23-year-old rapper recently collaborated with the singer on her song Birthday Cake earlier this year.
But the singer has previously insisted she will not stop seeing Chris just because other people want her to.
She explained: "I respect what other people have to say. The bottom line is that everyone thinks differently. It's very hard for me to accept, but I get it.
"People end up wasting their time on the blogs or whatever, ranting away, and that's all right. I don't hate them for it. Because tomorrow I'm still going to be the same person. I'm still going to do what I want to do."
