Rihanna was dining at a restaurant in New York on Monday night when she saw Bieber seated at a nearby table.
Rihanna was stunned when the Bieber lifted his top to show off his impressive abs, and she admits she found his cheeky flash "sexy."
In a post on her Twitter Rihanna writes, "Justin Bieber just flashed me his abs in the middle of a restaurant! Wow! He actually had a lil 6 pack! Sexy, lol (laugh out loud)!"
And Bieber was clearly happy with the compliment since he responded by posting a photo of the two stars together at the restaurant, adding: "It's always love."
