Life's a beach for Kourtney Kardashian.
The E! reality star snapped a selfie during her family vacation in Mexico on Sunday, Jan. 26. The shot offered up more than an eyeful of cleavage as she aimed the camera upward towards her chest.
Kourtney appeared to be in a sexy black string bikini, and accessorized with two gold necklaces and a pair of aviator sunglasses.
Lookin' good, Kourt!
Kourtney held onto baby Penelope, who was donning a seriously adorable bathing suit by PilyQ Barcelona.
Meanwhile, little Mason was seen running around and taking plenty of dips into the pool. Like the fashion-savvy toddler that he is, Mason sported a pair of tropical-themed trunks for the sun-soaked outing.
But it looks like reality has set in as Kourtney and her family headed back to the States following their beach vacation.
She Instagrammed a photo of herself lounging in a seat hanging from a palm tree that said, "Miss you Mexico."
