Kourtney Kardashian and Travis Barker have captivated fans everywhere with their whirlwind romance.
After publicly denying dating rumors, the reality TV star and the Blink-182 drummer made things official this year, sharing candid photos of vacations together, intense PDA and tattooed expressions of love on Instagram.
In May, Barker, 45, even referred to Kardashian, 42, as the "love of my life" in an Instagram comment on a post of the two at Disneyland. Kardashian has been similarly lovey back at him, posting a photo of her and Barker sharing a passionate kiss in a recording studio last month, along with two hearts and a fire emoji.
Barker was previously married to actress Melissa Kennedy from 2001 to 2002 and to model Shanna Moakler from 2004 to 2008, with whom he shares two kids. Though Kardashian has never been married, she shares three kids with her ex-partner Scott Disick. The two dated on and off from 2006 to 2015.
The couple have reportedly been spending time with each other's kids as well, and, over Memorial Day weekend, Barker even shared a video to Instagram of him going down a water slide with Kardashian's youngest son Reign, 6.
Here are some of the biggest milestones in the couple's love story:

“Kourtney’s like a dear friend. That’s it,” he told the outlet, shortly before opening the 2019 iHeartRadio Music Awards. "I mean, I love her to death. I love her family to death. But yeah, just friends."
The two confirmed their romance about two years later.
