Sources recently said that the father-of-three, who is currently dating 19-year-old Amelia Hamlin, ultimately wants his ex-girlfriend to be happy, but he “can’t help feeling slightly jealous.”
"He’s very protective over Kourtney, but ultimately, wants to see her happy,” an insider claimed.
Supposedly, Barker has already been introduced to the Kardashian family, including Kim, Khloé and Rob, who have welcomed the drummer of Blink 182 with open arms.
The famous clan is convinced that Barker and Kardashian make a great couple, and they’re also happy that the reality star has decided to date someone “more age-appropriate” than her previous exes.
Kardashian began dating the self-proclaimed Lord Disick in 2006 and ended their nine-year romance in 2015.
She shares three children with Disick — Mason, 11, Penelope, 8, and Reign, 6 — and though the pair haven’t been together in six years, they’ve continued to remain in close contact with one another for the sake of their family.
The Poosh founder has reportedly been dating Barker since December, sources tell E! News, and while fans were initially taken aback by the news, having found their pairing to be rather “odd,” Kardashian is said to be over the moon with how well things are going in her love life.
They were first spotted hanging out in Palm Springs, Calif., together earlier this month, and while their outing was first believed to be an innocent get-together, insiders have since confirmed that Kardashian and Barker are very much dating.
"It's been very low-key," a source revealed. "They are a really good match, and Kourtney's entire family already loves Travis. They have been neighbors and great friends for years, and it just recently turned romantic."
One thing that Kardashian admires the most about her beau is how much of a hands-on dad he is with his children, Landon, 17, and Alabama, 15, whom Barker shares with former model Shanna Moakler.
"Travis has always had an eye for Kourtney," the source continued.
"The chemistry and flirtation has always been there. They have a lot in common, and Kourtney has always been attracted to how Travis is as a parent. He's an amazing, hands-on dad, and Kourtney loves that about him.
"They love relaxing at home with their kids, and everyone gets along. It's going well, and they aren't putting pressure on it being super serious at this point."
Life & Style was the first to report of Disick's jealousy.
