Kourtney Kardashian isn't the only one stripping down on her girls' trip to Mexico!
As we've reported, the KUWTK star celebrated her 38th birthday Punta Mita, Mexico with her sister Kim Kardashian West, and besties including Larsa Pippen, Brittny Gastineau, Jen Atkins, Steph Shepherd, Hrush Achemyan, Joyce Bonelli, Sarah Howard, Malika Haqq, and Khadijah Haqq McCray.
The momma-of-three has been sharing racy snaps all week – and on Tuesday, one of her pals really cut loose by getting naked and rolling around in the pool!
