The 18-year-old model and the Saturday Night Live comedian were spotted packing on the PDA while poolside at a hotel in Miami, Florida, on Saturday. The two couldn't get enough of one another as they soaked up the sun and had a make out session before jumping in the pool where Gerber wrapped herself around Davidson, 26.
The two were casually dressed, with Gerber wearing a black bikini, blue button up and sunglasses. Davidson wore black swimming trunks, a beige t-shirt and black slides.
The PDA-filled outing comes after a source told ET that the two spent last weekend together at the SNL after-party in NYC, where they didn't hide their relationship.
"Throughout the night, they were very affectionate and flirtatious with one another," the source said. "At one point in the evening, Pete and Kaia were alone together in the back of the restaurant, in one of the booths. They were laughing with each other and exchanging flirtatious touches."
