Insiders claim Beyonce is sick and tired of Rihanna’s raunchy ways…

From The National Enquirer 

“Beyonce has considered herself one of Rihanna’s mentors since (her husband) Jay-Z signed Rihanna to his label in 2004.

And Rihanna has referred to Beyonce as a big sister.

“But Beyonce has worked hard to empower women with her music, and she feels Rihanna is undoing a lot of that work. She’s at the point now where seeing Rihanna grabbing her crotch on stage makes her feel sick.”

The “Umbrella” singer, 25, has been blasted for provocatively holding her microphone between her legs while performing in Amsterdam.

She also raised eyebrows when she posted pictures of herself on Instagram smoking two huge marijuana cigarettes.

Rihanna further ticked off Beyonce, 31, by showing up two hours late for her show in Birmingham, England, said the source.

“LEAVING fans waiting iks a no-no in Beyonce’s world,” explained the insider. “Jay’s very protective of Ri and doesn’t want to rock the boat, but Bey felt she wouldn’t be doing her job if she didn’t say something.”

“Crazy in Love” singer Beyonce has also advised Rihanna, who’s now on a world tour, to clean up her more scandalous antics, said the source.

“Bey thinks Rihanna is making herself look trashy for no good reason.”
