Kim Kardashian is a major fan of Kourtney Kardashian and Travis Barker’s newfound love.

Kim discussed their romance on Thursday’s episode of The Ellen DeGeneres Show. “I love their relationship,” she told Ellen. “They’ve grown so much together. … Just to think that they’ve been neighbors and friends for almost 15 years. Neighbors for like, a decade!”

DeGeneres joked that the pair can’t seem to “keep their hands off each other” since revealing their relationship to the public. “They are at each other like it’s the last time they’re going to see each other, all the time!” she added.

“It’s a lot, but it’s so cute,” Kim said. “You know what? That’s what they do, and it’s so cute. And I love love, so I love them.”

Kourtney and Barker confirmed their relationship back in February with an Instagram post of them holding hands. Since then, the duo has been all about PDAs, with them most recently making their red carpet debut as a couple at the MTV VMAs, where they shared a passionate kiss.

Kim and DeGeneres also discussed the possibility of Barker appearing in the Kardashian family’s forthcoming Hulu show. “I honestly haven’t talked to them about it, but I’m assuming because he’s such a big part of Kourtney’s life that hopefully they will be on,” Kim said.

“I will say this is the longest we haven’t filmed for,” Kim continued. “It’s crazy how since we’ve had this free time, all of the stuff that’s gone on—whether it’s, like, this relationship, or Kourtney’s relationship, or whoever’s. It’s, like, people have had this free time off and had these beautiful new relationships blossom, and it’s gonna be really fun and interesting to see filming dynamics and us back together.”

The family’s reality show Keeping Up with the Kardashians ended in June after 20 seasons and 280 episodes.
