Look back at it.
Kim Kardashian isn't the only Kardashian that can show off her greatest asset from time to time. Kourtney Kardashian flaunted her killer curves in this booty-friendly monokini while in Las Vegas recently, where she was spotted taking a dip in the pool to cool off from the heat.
Unlike Kim, Kourt's butt wasn't all oiled up for the cameras, but then again, this wasn't a photo shoot (although, the pictures do look really great, so who knows?!).
