While on a girls' trip to Tulum to celebrate sis Kourtney's birthday, paparazzi photographed Kim Kardashian, who was in a revealing (read: standard) bikini that showed off her butt. As bikinis tend to do.
We know. This isn't news. We've seen Kim's famous butt what, like, a thousand times? If you follow her on any of her social media accounts you know that mirror pics in little to no clothing are a pretty regular occurrence. In fact, she posted a pic of herself in the same vintage Dior bikini on her own Snapchat.
