Inside Rihanna's Feud With CBS Sports

The singer had choice words, including an obscenity, for network. Here's why.

— -- Rihanna has always been one to speak her mind.

This morning, nobody knows that more than CBS Sports.

"CBS you pulled my song last week, now you wanna slide it back in this Thursday? NO, F*** you! Y'all are sad for penalizing me for this," she tweeted. "The audacity..."

A rep for her label, Roc Nation, added in a separate statement, "Due to the misuse and misrepresentation of Rihanna's name and participation in connection to CBS' TNF [Thursday Night Football], CBS was not allowed to license and utilize the song 'Run This Town.'"

"It’s important to realize we are not overreacting to this story but it is as big a story as has faced the NFL," CBS Sports chairman Sean McManus told the magazine at the time. "We thought journalistically and from a tone standpoint, we needed to have the appropriate tone and coverage. A lot of the production elements we wanted in the show are being eliminated because of time or tone.”

The network never said publicly whether it would use the song after last week’s cancellation, but it’s now clear that "Run This Town" is out of the picture.

"Beginning this Thursday, we will be moving in a different direction with some elements of our Thursday Night Football open," a CBS Sports rep told ABC News in a statement. "We will be using our newly created Thursday Night Football theme music to open our game broadcast."
