Sofia Richie Shares Steamy Kiss with Scott Disick during romantic holiday in Mexico

Sofia Richie and Scott Disick appear to be head over heels in love.

Disick, 34, and Richie, 19, spent the majority of Monday in Puerto Vallarta, Mexico, basking in the sun and engaging in some serious PDA.

During an action-packed day in the sun, the 34-year-old was seen planting a series of kisses on his partner.

The couple kissed while riding a jet ski together. While the photo taken by the paparazzi is adorable and a perfect gram moment, I’m a little distracted by the fact that the jet ski is moving.

Sofia looked stunning in a pair of little yellow bikini bottoms and a red top, which highlighted her slim form.

The 19-year-old model couldn’t help but post a few photos of her PDA-filled holiday with the reality star on social media.

“Taco night,” Richie captioned a photo of herself snuggling up to Disick while a mariachi band played behind them on her Instagram Story.

After spending a weekend away together in September, Us Weekly announced that Disick and Richie had become a couple.

Richie enjoys having Disick around, according to the insider, and the kid has put a name on their relationship.

“Sofia calls Scott her boyfriend,” a source said. “She thinks he is the best.”

These two adore spending their holidays at the beach. They got together with a group of pals in beautiful Miami, Florida, last month and shared a lot of kisses at a group meal.

The new display of passion comes after Kourtney Kardashian, Scott’s ex and mother of his three children, was left saddened by the trip, which sees them staying at the same villa where they first met, according to The Sun Online.

According to a source, Kourtney, 38, returned to Los Angeles after a trip to Paris with boyfriend Younes Bendjima.

“She had another amazing vacation with Younes, but she really missed her kids,” a source said. “She seems very excited that her sisters are pregnant. They are all already talking about baby showers. Khloé and Kylie are asking for baby nursery advice. It’s like it’s bringing the sisters even closer together.”
