Travis Barker shares racy, NSFW birthday tribute to Kourtney Kardashian for her 42nd birthday

Travis Barker is truly head over heels for Kourtney Kardashian and he let the world know with his birthday tribute to his 42-year-old girlfriend.

Barker shared a tribute to Kardashian on Instagram on Sunday and the caption read, “I F**KING LOVE YOU! YOU’RE A BLESSING TO THIS WORLD HAPPY BIRTHDAY @KOURTNEYKARDASH.”

The first picture shows Kardashian and Barker kissing on a couch and the rest of the posts were full of PDA shots. But that last slide… threw everyone for a loop.

Barker shared an NSFW video of the Keeping Up With the Kardashians star sucking his thumb suggestively before falling back and laughing. “Travis,” Kardashian says in the racy video.

Many people on social media were shocked by the video of Kardashian and Barker’s thumb because… what did we just see?!

Kardashian's sister Khloé commented on the post and said that the couple gave her serious Bridgerton vibes. “The Duke and the Duchess!!!!!!!!!!! Bridgerton vibes," the Good American founder wrote.

Earlier in the day before we were all gasping at Barker's post, Kardashian shared an amazing floral display that her boyfriend had bought her for her birthday. Even Kim Kardashian was jealous! The lavish floral display included white tulips and green moss in a vase with white gardenias hanging FROM 👏 THE 👏 CEILING 👏.

“Tulips and gardenias are my favourite flowers,” she wrote on her Instagram Story. “My entire house smells yummy.”

Kim, who was once gifted a flower wall, was very jealous of Barker's grand gesture. “I just walked into the most gorgeous flower arrangement,” Kim said in a video of her sister's flowers posted to her Instagram Story. "This is so beautiful. I’ve never seen anything like this.”

Barker also shared a photo of a plate of dessert with a birthday candle inside a strawberry. It had the words "Happy Birthday Kourtney" written in chocolate syrup across the plate. Kardashian reposted the photo and wrote, "My first birthday wish."

The Blink-182 drummer didn't stop there. He also shared a photo of Kardashian laying on top of him at the beach.

Barker and Kardashian are living our full-on PDA dreams and people on Twitter are here for this relationship.

Kardashian and Travis began dating in January before making things Instagram official in February. They recently took their first family trip together to Deer Valley, Utah, with their respective children and it doesn't seem like the couple is slowing down anytime soon.
