Love is literally in the air for Scott Disick and Sofia Richie. Ever since they made their relationship Instagram official late last month, the couple has been flaunting some serious PDA on and off social media, with them most recently sharing a passionate kiss aboard an airplane.

Sofia shared on Instagram Stories on Sunday, October 8 a photo of the intimate moment. Wearing casual outfits, the new lovebirds could be seen leaning in for a smooch as they held hands while they were seemingly in the middle of enjoying their meals.

Scott and Sofia were first romantically linked to each other earlier this year, in May, during Cannes after they were seen getting flirty on a yacht. She quickly denied it on Twitter, though, writing, "Just so everyone can get their panties out of their asses, Scott and I are just homies #relax."

The model daughter of Lionel Richie insisted that her relationship with the self-proclaimed Lord of party was strictly platonic when they were spotted together again. "The last time I'm gonna say it. Scott and I are just friends. I'm single and focused on friends, family and work. #againrelax," so she told her online followers.

The pair finally confirmed their romance when they paraded major public display of affection on a boat following a night of partying with Kylie Jenner's rumored baby daddy Travis Scott (II) at LIV nightclub.

Scott posted on Instagram Stories a picture from the outing, showing him nuzzling Sofia's neck. His new girlfriend shared on her own page an image of their dinner table. They ate a fancy dessert delivered with a sparkler and message, "Congratulations Scott and Sophia [Sofia]."

In viral videos on social media, the restaurateur and the aspiring model were seen playing tonsil hockey. As they made out, their friends held up their cellphones to record the moment and cheered on the new couple.
