On this week’s episode of The Kardashians, the Lemme co-founder and her drummer husband travel to Australia as they join Barker on Bline-182’s world tour. While the family goes on a boat together in Sydney, Kardashian Barker and Barker begin making out.

“Mom, stop making out with Travis, bro. Like didn’t you just have a 𝚋𝚊𝚋𝚢? Don’t get another one this quick,” Kardashian Barker’s son Reign, 9, can be heard saying.

In a confessional, the mom of four says that she thinks it’s a “beautiful thing” for her kids to see her so in love.

“I think it’s a beautiful thing to see parents, especially ones that just had a new 𝚋𝚊𝚋𝚢, be affectionate and loving. There’s nothing wrong with that,” Kardashian Barker says.

The scene switches back to the boat, where Reign is still upset.

“Are you giving her a hickey right now?” Reign asks Barker, to which he says no.

“It was just a gentle kiss on my neck. I missed him,” Kardashian Barker responds, as Reign makes a disgusted face at the camera.

Earlier this week, Kardashian Barker celebrated her daughter Penelope’s 12th birthday, sharing a video on her Instagram. “12 years young 🎈🌴🎡☀️🌊💘,” her caption read as the video played alongside Zaz’s cover of “La vie en rose.”

The video began with a birthday cake that featured white icing, flowers and 12 candles. “Happy Birthday Penelope!,” the cake read as it rested on a cake stand beside a plate of star and circle-shaped sugar cookies.

The compilation of clips then switched to the beach and a pair of black Vans sneakers lying in the sand as Penelope and her friends frolicked in the water in the background.

New episodes of The Kardashians drop every Thursday at 12 a.m. ET on Hulu.
