How Katy Perry, Rihanna became best friends

SINGERS Perry and Rihanna revealed that they became "fast friends" after bonding over a purse in 2009.

Perry explained how she met the Umbrella singer, who not only threw her a bachelorette party before she married Russell Brand but also reportedly comforted her after their Dec. 30 split.

"[Rihanna] had this cool studded Valentino bag that had sparkly stuff on it," Perry told Elle magazine.

Apparently, when Perry complimented her on the purse, the Barbadian pop star offered to send Perry the same one as a gift.

"I was like, 'Oh great, here's one of those tricks who talks fast friends but never lives up to it,'" Perry said, revealing that she was initially skeptical. But Rihanna followed through on her promise.

"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.'"

Rihanna was surprised that her friend remembered that moment.

"She remembered that? That's awesome!" Rihanna told the US magazine.

"I'll tell you, you do not find people like her in this industry. She's gorgeous, charming and so unedited it's scary. That's what intrigued me most when I first met her - she said it like she saw it. I trust people like that."

Rihanna's interview is published in the May edition of Elle.
