The 25-year-old model and the Phoenix Suns basketball player packed on the PDA during their Italian vacation. This week, the couple was spotted at a restaurant in Salerno, with Jenner giving her boyfriend a sweet kiss on the cheek.
In the snaps, the model wears a white tank and dark sunglasses as she cuddles up to Booker, 24. The athlete, seen in a white t-shirt, is all smiles as she shows him affection. After enjoying their meal, the two headed back to their yacht to continue soaking up the sun.
Jenner has been sharing little peaks inside their getaway on her Instagram. Earlier this week, she wowed in a lime green gown while on the boat.
While Jenner and Booker have been going strong, a source told ET the pair aren't putting pressures on their relationship.
"Devin Booker is sweet, smart, fun and totally not a player," the source said of the NBA star. "He is very respectful and was raised with very good values. Kendall finds that to be a very attractive quality."
"They can both balance work and their personal lives together, and it's not an issue," the source added. "They're not putting any sort of pressure on things for the future. They realize they're both still young and have big futures ahead of them. Right now they're just enjoying their time together and taking things as they come."
Most recently, in a rare Instagram, the Olympian shared a slideshow of snaps from a lakeside vacation, in which Jenner rocked the gold medal he won as a member of Team USA's basketball team at the Tokyo Summer Games earlier this month.
