Pop star Rihanna has blasted a US television network for wavering on whether to use one of her songs in its American football broadcasts, amid a furore in the league over domestic violence.
CBS had planned to play Jay-Z's Run This Town, featuring Rihanna, at the start of its season-opening on Thursday Night Football program, which last week featured the Pittsburgh Steelers against the Baltimore Ravens - whose star Ray Rice has been banned from the National Football League over allegations he knocked out his now-wife.
CBS dropped the song, as well as a comedy segment, citing a need for the "appropriate tone" to the broadcast. Apparently, it had the intention to use it in the opening of this week's program.
But Rihanna - herself the victim of a highly publicised 2009 assault by singer and then-boyfriend Chris Brown - wasn't impressed with the move.
"CBS you pulled my song last week, now you wanna slide it back in this Thursday? NO, F*** you!" Rihanna wrote on Twitter.
