Pop singer Rihanna was very disappointed, to say the least, when CBS scrapped her opening number from last week's "Thursday Night Football" to give way to the league's explanation on the Ray Rice issue.

The change in the show format did not apply to other portions of the show as most of the original parts of the program were retained except for Rihanna's song and a comedic skit. 

The singer went on a rampage on her Twitter account, letting all her frustrations out as she tweeted: "CBS you pulled my song last week, now you wanna slide it back in this Thursday? NO," followed by an expletive. She ended her tweet with, "Y'all are sad for penalizing me for this."

In a similar report, TMZ said the singer's anger stemmed from her claim that the league and the network "had no right to make it look like she was part of the Ravens/Steelers pre-game show" and that they "had no right to single her out by" not allowing her to perform her song.

TMZ sources also claimed that Rihanna got angry with the title of the release of the show which read "CBS & NFL Network 'Run This Town' for Thursday Night Football Open with Music Featuring Rihanna & Narration by Don Cheadle." The sources noted that the network licensed a Jay Z song featuring Rihanna, and nothing more.

A representative of Rihanna informed TMZ that because of the "misuse and misrepresentation" of the singer's name in connection to CBS TNF, the network "was not allowed to license and utilize the song 'Run This Town.'"

"Roc Nation made the decision to not grant the song's usage," the representative added in a statement.

It was explained by CNN that Rihanna made a special recording of "Run This Town" for CBS fall telecasts of "Thursday Night Football," but because of the turn of events, the network responded by announcing that they will not be using the song anymore for the rest of the season.

Washington Post noted that Rihanna is not afraid to speak her mind on social media especially if she feels she was wronged. The report cited the incident when Ciara commented that Rihanna wasn't very nice and the latter replied with "My bad ci, did I 4get to tip you? #howrudeofme."

She has also defended herself from negative comments on Instragam and has responded to not so pleasant headlines or stories about her and her choices.
