Kourtney Kardashian celebrated her 42nd birthday on Sunday.
This birthday so happens to be the first she's sharing with new boyfriend Travis Barker, 45. The Blink 182 drummer celebrated his love on Instagram with a photo collection.
One snap showed the Barker's tattooed hands around the lower waist of his Keeping Up with the Kardashians girlfriend, as she wore a two-piece black swimsuit.
The new couple, who share five children between them, have been linked since February.
"I F***ING LOVE YOU! YOU'RE A BLESSING TO THIS WORLD HAPPY BIRTHDAY @kourtneykardash," Barker captioned the slideshow.
The drummer's first image showed him holding the POOSH founder as they passionately kissed while she sat on his lap.
Travis was dressed in a white graphic-printed t-shirt, as he rocked a pair of dark gray jeans and a bright red beanie. Kourtney was seen wearing a crop-top above a sequined skirt that featured a long fishnet-like bottom. The mom-of-three finished the cute look with a pair of black shoes.
Barker and Kardashian were also seen making out in a separate photo that featured a darker orange hue.
In another shot, the couple were seen hugging each other while keeping themselves warm in front of a roaring fire pit.
Travis kept it casual in a pair of black jeans and a matching graphic-printed t-shirt.
Kourtney's wore a light beige button-up jacket and a pair of colored pants.
The drummer's third photo showed him lightly touching the bottom of his girlfriend's foot while also showing off her tanned legs.
But it was the video Travis shared in his collection of images that shocked fans.
The musician added in a wild clip of the reality star sucking on his thumb.
He taped the intimate moment with Kourtney as the camera flashed in her face and she laughed, saying: "Travis!"
Some fans criticized Kourtney and Travis were over the content.
"That video of her sucking his thumb and the fact that they did it for social media is disgusting. I'm sure her son Mason's friends are enjoying it," one fan wrote.
"Mom can't keep it classy, not even for her children," a second added.
"You wouldn't treat a woman you are meant to love & respect showing photographs like this," a third chimed in.
"The finger sucking video is absolutely vile, no one wants to see it," a fourth commented.
Meanwhile Travis sent his birthday girl an eye-catching floral display.
Kourtney arrived at her home to find a sizable display of white flowers, which she posted for her 116 million fans on her Instagram stories.
