Scott, 35, put his arm around Sofia while they took in the breathtaking views in Capri.
Sofia, 20, stunned in a pair of white shorts and top that exposed her firm midsection.
She showed her body off even further later on in the day in a sexy bikini.
Scott and Sofia appeared to be enjoying each other's company during Kylie's big birthday weekend.
Travis Scott, Kris Jenner and many others were in the European country to celebrate Kylie's 22nd birthday.
Sofia looked to be a good shoulder for Scott to lean on after his new reality show Flip It Like Disick tanked in the ratings.
The E! program brought in just 455,000 viewers for its August 4 premiere, which landed it in the 63rd spot out of the top 150 original cable shows, according to Show Buzz Daily.
"Scott is just extremely upset about this. Anyone who knows Scott knows that he put his entire heart and soul into the project," a source told RadarOnline.com.
