Kourtney Kardashian and Travis Barker make out backstage at his Blink-182 concert in Sydney

Things are getting hot Down Under.

Kourtney Kardashian and Travis Barker were seen making out backstage after Blink-182 finished a show at the Qudos Bank Arena in Sydney, Australia over the weekend.

A fan-filmed video showed the couple passionately making out, hugging and lovingly gazing into each other’s eyes before getting interrupted by Barker’s bandmates, guitarist Tom DeLonge and bassist Mark Hoppus.

The happy couple was recorded by a fan passionately making out after Blink-182’s Sydney, Australia show over the weekend. They also hugged and lovingly stared into each other’s eyes.

They seemed to mock the happy couple, as Tom DeLonge jokingly planted one on the drummer’s cheek before surprising Hoppus from behind and hugging him.

Kardashian, 44, rocked an oversized white and red football jersey that had “Mr. Chasin a Dream” printed across the front in black lettering. The jersey retails for $300 on NAKED Copenhagen’s site.

She paired it with lace-up black heels and no pants. She kept her thick brunette hair out of her face with a thick headband.

They were lovey-dovey until Barker’s bandmates mocked them.

The Poosh creator has been in the land down under supporting Barker, 48, and his bandmates as they tour through Australia and New Zealand. They have six more Australian dates — including two more in Sydney — before they fly to New Zealand, according to the pop-punk band’s tour schedule.

She showed that three of her kids — Penelope, 11, Reign, 9, and Rocky, 4 months, tagged along in a carousel she shared on Instagram Monday.

While Rocky’s face was not visible, he was likely in the baby carriage the reality star looked down lovingly at in one of the photos she shared. It’s possible her eldest, Mason, 14, also traveled with her, but he was not pictured.

Kardashian shares her three eldest kids with her ex, Scott Disick, while she and Barker welcomed their baby boy last November.

The mom of four was spotted visiting a farm with Penelope, Reign and Rocky earlier this week and had a camera crew following them. It’s unclear if the footage was being captured for Hulu’s “The Kardashians” or another project.
