The Blink-182 drummer paid his respects to his wife's late father with this thoughtful gesture.

Travis Barker has proven he is a true romantic—especially when it comes to Kourtney Kardashian.

In the most recent episode of The Kardashians, now playing on Hulu, Kris Jenner revealed that the former Blink-182 drummer visited Robert Kardashian Sr.'s grave to ask for permission to marry his eldest daughter. He phoned Jenner asking for her permission as well.

Jenner recounted the emotional moment to Kim Kardashian in her dressing room during rehearsals for her performance on Saturday Night Live and they teared up at the loving gesture from Barker, who continues to show he is willing to do anything for the 43-year-old.

"He asked for her hand in marriage, and I was like, literally, I want to cry now," Jenner said while getting her makeup done. "It was so sweet and so tender. And then he said he went to your dad's grave and asked your dad [for permission], and I just lost it."

Jenner added that, "It's all happy, I just wish your dad was here to see it. I can hardly believe that it's the first time that she's getting married."

Despite Kourtney's relationship with Scott Disick for more 10 years, they were never married. Barker has been married twice before to Melissa Kennedy and Shanna Moakler.

"That's really crazy that she hasn't been married before," Kim joked. "While I've had enough for all of us!"

Barker proposed to Kourtney on October 17 at Montecito, California at the Rosewood Miramar Beach hotel. Kardashian was taken by surprise as he popped the question on the beach at sunset while surrounded by red roses in the shape of a heart and candles.

"forever @travisbarker," Kourtney wrote on social media after the proposal.
