Bad Gal Riri was flying first class when she shared a hilarious video of her chance encounter with McCartney to her Instagram story.
"I’m about to put you on blast Mr. McCartney," Rihanna said as she started filming Paul.
"Who is this filming me?" McCartney jokingly replied before Riri laughed and said, "Who is this peasant filming this legend?"
Rihanna and Paul are good friends and have worked with each other in the past. They collaborated on the song "FourFiveSeconds" with Kanye West in 2015 and have remained friendly.
