Someone get these two gals BFF necklaces STAT -- but I guess instead of matching necklaces a little booty grab can easily do the trick as well! What do you think of RiRi's way of displaying her friendship?
Cara Delevingne, 20, took to Instagram on July 19 to express her love and gratitude for best friend Rihanna. She captioned a photo, which displayed a little booty grab, saying: "Thank you my boo @badgalriri for always making me smile and of course for keeping my bum cheek warm." Rihanna and Cara, both in bikinis in the picture, look great --even from behind!
