The 25-year-old singer shared a picture with Katy on her Instagram page with the caption: “She. X She. #Katy #RIHunited.”

In a recent interview with Elle, Katy Perry opened up about her friendship with Rihanna.

“I love her and every time I see her, I’m reminded of the light that she has,” the singer said.

Perry also revealed in an interview with Elle back in May 2012 how she and Rihanna became best friends in 2009 after bonding over a purse.

“[Rihanna] had this cool studded Valentino bag that had sparkly stuff on it,” Perry recounted at the time.

And when Perry complemented her purse, Rihanna offered to send her the same one.

“I was like, ‘Oh great, here’s one of those tricks who talks fast friends but never lives up to it,'” Katy said.

“Valentine’s Day came around, and I got a little Valentino bag in the mail from her,” Perry said. “I thought, ‘Wow this is a woman of her word.'”

Nice gesture, indeed!
