Travis Barker and Kourtney Kardashian may have seemed like an unlikely couple when we first heard of their steamy romance (opens in new tab).

Take, for example, this latest exchange: Kardashian posted a photo and video on Instagram (opens in new tab) that included a video of the two holding hands over a restaurant table. She captioned the post "skies n' stuff." In the comments section, Barker wrote, "Laughing with you for the rest of my life." She replied, "The rest of my life." For the record, I'm allergic, so I'm definitely not crying.

The lovebirds have long been rumored to be discussing marriage (open in new tab), and Barker also got a tattoo of Kardashian's name (open in new tab) in April, so you know they are really serious. They also spend an inordinate amount of time making out (opens in new tab) and are really not shy about it. Not only do they regularly post PDA (opens in new tab) filled photos on social media, but they also had a photo shoot (opens in new tab) while making out next to Megan Fox and Machine Gun Kelly (opens in new tab) in the VMA (opens in new tab) bathroom. Classics.

Kardashian and Fox capitalized on the buzz they created with these bathroom photos by posing together for a very sexy Skims campaign (opens in new tab).
