We had no idea about the feud between Rihanna and Rita Ora.
Rihanna held a Met Gala after party at Up & Down nightclub in New York City on Monday following the Met Gala at the Metropolitan Museum of Art.
For some reason, the singer refused to give Rita Ora an invitation to the event, which was attended by celebrities such as Kylie Jenner and Justin Bieber.
A source told the Sun: "She has a real issue with Rita and this was her chance for revenge."
"She made it clear when organising her party that Rita was not to gatecrash under any circumstances," they added.
The 27-year-old reportedly spent a lot of the night hanging out with Cara Delevingne, Rita's ex best friend which caused an awkward atmosphere between the 24-year-old and the model.
A source said: "It was very icy between Rita and Cara. They spent the night trying to ignore each other. Rita decided to hang out with Miley Cyrus instead. She was never going to attend Rihanna's party because she'd made plans to go to another bash."
Rita ended up at Lady Gaga's after party at the Diamond Horseshoe nightclub instead.
Hmmm, we wonder what drama has previously gone on there…
