Rihanna vs. Beyonce Beef, 'Creeping' Scandal: Jay-Z Calls Roc Nation Beauty on Private Phone, Baby Blue Ivy's Mama 'Livid' With Secret Flirting?

Apparently, Beyonce thinks that Jay-Z's growing business relationship with Rihanna is growing WAY too personal.

The "FourFiveSeconds" songstress is definitely one of HOV's most successful protegees, so it's no wonder that he gives the 27-year-old Barbadian beauty so much attention. But rumors now suggest that the Magna Carta superstar has a private phone that he only uses to correspond with RiRi. Taking things too far, perhaps?

Especially now that Queen Bey's discovered Jay's little mobile secret.

An alleged insider tells UK's Grazia magazine:

"Jay has several phones, one of which he keeps reserved for Rihanna, supposedly to discuss business interests... It's obvious when she calls because he'll interrupt meetings, even walk away from the dinner table to speak to her" (via Daily Mail).

The Destiny's Child muse was never close pals with the infamous #BadGal. Wonder why?

Meanwhile, the Roc Nation mogul heatedly denies every indulging in a hot-and-steamy fling with Drake's ex-lover. They just work together - a lot!

The "Drunk In Love" sweetheart was supposedly well aware that her hubby had several different phones. But she was livid after learning that he had a specific device that he only uses with Rihanna.

Maybe this explains why Bey and the "Home" starlet never hang-out, nevermind collaborate together.

Does Blue Ivy's mom have a reason to be so worried?

Twitter's constantly abuzz surrounding this viral hip-hop "rivalry" -

@MadonnaARMY1: "Rihanna is better than beyonce in every single way."

@kaybentler: "I had a dream I was at a Rihanna concert and Beyonce was there taking selfies w everyone."

@lizadye: "imagine if rihanna could dance as well as ciara and ciara could sing as well as beyonce and beyonce could read as well as a child."

@Juicy__Nae: "Beyonce is a better singer, actor, dancer and is by far classier than Rihanna #BeyHive [Queen]."

@trippysix: "am i the only person who feels like rihanna > beyonce."
