Megan Fox and Kourtney Kardashian are not shy about telling the world just how much they love their boyfriends.

Fox, 35, and Kardashian, 42, hit the stage at the MTV Video Music Awards together on Sunday to introduce Machine Gun Kelly and Travis Barker, who performed their single "Papercuts" together to close out the show.

"I'm a huge fan of this next performer. I've watched him grow, and not just as an artist, but also as a person," Fox told the crowd of Kelly, 31.

"I'm a fan too, and I think his drummer is super hot," Kardashian quipped of Barker.

Fox then sent tongues wagging as she introduced the musicians in a very special way: "New York, I need you to get extra loud for our future baby daddies," she told the crowd.

Kelly — who won the best alternative Moon Person for "My Ex's Best Friend," featuring Blackbear — wrapped up the show with an intense performance of "Papercuts" in which he smashed his pink guitar at the end.

The pair made their relationship Instagram official in February, and both also have three children: Kardashian shares sons Mason, 11, and Reign, 6, and daughter Penelope, 9, with ex Scott Disick, while Barker is dad to son Landon, 17, and daughter Alabama, 15, with ex Shanna Moakler, and considers Moakler's daughter Atiana, 22, his own as well.

Kelly debuted "Papercuts" with Barker in August as the lead single from his upcoming sixth studio album, Born with Horns, which the Blink-182 drummer executive produced. (The pair previously worked together on Kelly's September 2020 album Tickets to My Downfall.)
