Kris, 63, and Corey, 38, took to the sea in Monte Carlo.
They were all smiles while cuddling up on board their yacht.
Corey was seen grabbing at his ladylove's butt at one point while she tried to walk around the vessel!
Kris and Corey have been enjoying a romantic summer together in and out of Italy.
They were in the island of Capri for her daughter Kylie Jenner's 22nd birthday last weekend.
The KarJenner matriarch was seen in a variety of colorful ensembles in early July 2019 with Corey in Portofino.
They consistently appeared to be having a blast with one another during their time in the European country over the past two months.
