Ed Sheeran and Katy Perry have total friemistry (friend chemistry)!

The "Shape of You" singer crashed the "Chained to the Rhythm" songstress’ BBC 1 Radio interview before the BRIT Awards on Wednesday, and the two got along like old pals.

"Thanks babes for keeping me off the number one spot," laughed Perry, noting Sheeran's single's current place on top of the Billboard Hot 100.
