It looks like there might be some bad blood between Rihanna and Cardi B. The end result? Riri allegedly uninvited Cardi from her epic Diamond Ball, which happened last week. 

As reported by MediaTakeOut, someone in Rihanna's circle are saying that Cardi's public altercation with Nicki Minaj at the Harper’s Bazaar ICONS party caused Rihanna to take back the invite. According to these sources, Cardi thinks Riri is "hating" since she has a competing makeup line. 

If these rumors are true, it seems pretty likely that this drama won't be going away anytime soon. 

Rihanna, Queen of Fentyland, holds an annual fundraising event called the Diamond Ball.

The Diamond Ball raises money for the Clara Lionel Foundation, in honor of her grandparents Clara and Lionel Braithwaite.

This year, Issa Rae hosted the event and Childish Gambino gave a special performance.

Tiffany Haddish, Trevor Noah, Paris Hilton, Nicky Hilton Rothschild, A$AP Rocky, and others attended the star-studded soirée.

But someone was noticeably absent from the affair: Cardi B.

According to MediaTakeOut, sources close to Rihanna say that Cardi B was uninvited from the event altogether.

Allegedly, the reason was Cardi's very public altercation with Nicki Minaj at the Harper’s Bazaar ICONS party earlier this month. 

"They told Cardi not to show up, and told her that security would not allow her in to the event," the source told MediaTakeOut

The insider went on to say, "Cardi thinks that Rihanna is just hating because she has a competing makeup line. When [Rihanna's] people told Cardi of her decision, she was like, 'F*ck Rihanna and the Ball.'"

Inevitably, the internet has a lot of opinions about all of this drama.

One person pointed out that several celebrities have reportedly unfollowed Cardi B on Instagram.

Another Twitter user said the way Rihanna handled the whole fiasco is "a mood."

But don't forget, Cardi was at last year's Diamond Ball looking very princess-like.

Hopefully this mean that the two superstars will put their differences aside in time for next year's event.
