Kourtney Kardashian and Travis Barker are no longer hiding their love on social media.  After the Blink-182 drummer serenaded Kourtney for her birthday, the Keeping Up With The Kardashians star took to Instagram to share a steamy PDA-packed pic from their latest getaway. From the looks of it, Travis can't keep his hands off Kourtney and her thong bikini.

In recent weeks, the Poosh founder has increased her PDA with Travis online. She shared her amazement at the extravagant flower arrangements he sent for her birthday. He dedicated a number of posts to her throughout the day, including a photo slide that included a naughty video of Kourtney sucking his thumb. While their followers continue to praise their relationship, sources say their romance is causing family drama behind the scenes. On Kourtney's end, she's having to deal with reluctance from her kids and their father Scott Disick. Insiders have claimed her children are "grossed out" by seeing their mom so affectionate with another man.

But that hasn't stopped the new couple from putting on a show for whoever is watching. After a weekend in the desert with the "All The Small Things" rocker, Kourtney shared a sultry bikini photo with her beau. "Just Like Heaven," she captioned the pic that showed Travis holding her while they passionately kissed. His arms covered the parts of her body that made the barely nude pic appropriate to post on Instagram. In response to her caption, Travis left a comment with a black heart emoji and called the moment "Everything."

There's no denying how into each other the new couple is. Insiders have shared how happy the two are together despite the skepticism from their exes. Most recently, sources revealed that Travis's ex-wife Shanna Moakler finds his public displays for Kourtney to be "hurtful" due to him having done the same things for her in the past. Meanwhile, Kourtney's ex Scott is still "getting used to" seeing the two in a relationship after they spent years as friends. Despite reports of Kourtney's kids being turned off by her current courtship, insiders first claimed it was Travis and Kourtney's kids who helped bring them together.

The two families spent years as neighbors and would often hang out together. But with Kourtney's kids being much younger than Travis's teenage kids, insiders say Kourtney knows her children will eventually adjust. They've been seen spending time with Scott and his 19-year-old girlfriend Amelia Hamlin. Insiders say Travis has been a "gentleman" with the Disick kids. But their latest PDA pic shows they're unbothered by all the hearsay.
