WATCH: Kourtney Kardashian and Travis Barker slammed for raunchy behaviour at friend’s wedding

Lovebirds Kourtney Kardashian and Travis Barker are known for their steamy public displays of affection.

For the most part fans celebrate their intense romance but it seems this time the couple may have gone too far.

A video of the reality TV star and Blink-182 drummer taken at a friend’s wedding has rubbed people the wrong way, with many calling them “tasteless”, “classless” and “embarrassing”.

In the clip, which was shared to comedian Claudia Oshry’s Instagram stories, Kourtney can be seen straddling a seated Travis, who is gripping her bottom

Blink-182’s hit song from 2000, All The Small Things, can be heard playing in the background as Kourtney gives her beau a sexy lap dance.

The video was shared on Reddit and prompted a slew of comments from users slamming Kourtney (42) and Travis’ behaviour.

“Oh no, why is she dry humping him in public let alone at someone’s wedding?” one user commented.

Another called it “tasteless, classless and gives teen hormones vibes”.

“This. . . is too far," said another. "So embarrassing for her life and her soul.”

Earlier in the day, Kourtney shared a picture of her and Travis (46) on their way to the wedding of her best friend Simon Huck and his partner Phil Riportella.

“Going to the chapel,” she captioned a series of images of her and the musician.

Kourtney looked stunning in a tight-fitted, cut-out black dress while Travis kept it sleek in a tailored black suit.

“Our turn next,” Travis commented on his fiancée’s post.

Turns out fans aren’t the only ones cringing about the couple’s over-the-top affection.

Kardashian family matriarch Kris Jenner told Ellen DeGeneres during an interview that she sometimes feels uncomfortable around them.

“Well, you feel like you’re, you know, they’re the only two people in the room, and we almost don’t know what to do with ourselves,” Kris told the talk-show host.

“Like, I’m looking for a closet to hide in and somewhere to go. But they’re. . . you know, they’re in that stage, and it’s really, really special and I’m so excited.”
