On this week’s episode of ‘The Kardashians,’ the 9-year-old pleads with his mom to stop making out with stepdad Barker

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.
