The 42-year-old Keeping Up With The Kardashian star looked crazy in love as she was seen gluing her body onto her rocker/ possibly fiancé's frame.
The two snuck away to the coastline beach, and a paparazzi caught all the action as Kourtney packed on the PDA.
At one point, Kourtney climbed on top of Travis and straddled him for all to see.
We should point out that the Poosh founder wasn't wearing a bikini for their beach day.
Instead of flaunting her body per usual, she was photographed wearing yoga pants and a long-sleeved top.
It's an interesting wardrobe choice for the beach -- especially amid pregnancy rumors.
Not only are Kourtney and Travis keeping hush about their possible engagement, but they haven't denied speculation that they might be expecting either.
Their PDA session on the beach just adds fuel to the fire.
Kourtney is allegedly set to become Mrs. Travis Barker after the Blink-182 drummer allegedly popped the question earlier this month in Las Vegas.
“I think Travis has been planning the proposal for ages,” a source told The Sun, adding their "intimate" wedding will take place later this year.
Besides potentially gearing up to walk down the aisle, fans also think the KUWTK star has a bun in the oven.
Travis continued to turn the rumor mill when he was caught lovingly rubbing her stomach, not knowing that paparazzi was nearby to capture the tender moment.
Kourtney's followers believe she's been dropping hints on social media with her vegan sushi and the fact she drank water out of a martini glass.
She's also been sporting baggy clothes lately -- an unusual move for any Kardashian.
After returning from Vegas, Kourtney was showered with white roses from her sister Khloé. Travis' daughter, Alabama, gave a loving shout-out to her potential stepmom-to-be too.
Despite keeping quiet on the baby and engagement rumors, Kourtney knew what she was doing when she was spotted wearing a giant diamond days after their Sin City getaway.
