On the surface, Kourtney Kardashian and Travis Barker are a bit of an oddball couple. 

She's the fashionista diva who's spent the past decade raising her children like they're royalty.

He's the heavily-tattooed punk rock drummer who's spent most of his adult life playing for sold out arenas all over the world.

But against all odds, it looks like these two have gone from hook-up buddies to full-blown boyfriend and girlfriend.

And now, they want the whole world to know that they're more than just friends with benefits.

We learned back in January that Kourtney and Travis are hooking up.

And it seems their relationship has proigressed quite rapidly in the weeks since.

Travis and Kourtney became Instagram official shortly after Valentine's Day, and since then, they've made no effort to conceal their love from the world.

In fact, over the weekend, Travis executed a more romantic public gesture than Scott Disick attempted in the ten years he was with Kourtney.

To the surprise of many fans who had already written the couple off as a flash in the pan, Travis recently shared a pic of a handwritten love note he had received from Kourt.

"To lots of fun adventures, may we destroy each other completely. Love, [heart scribble] Kourtney," the note read.

Yes, it seems that Koutney and Travis are already throwing the L word around.

Fans are still so confused by the relationship that they're googling "who is Kourtney dating?" in staggering numbers.

Although this might be a result of the fact that members of generation Z are too young to remember the heyday of Blink 182, so they're curious about what it is that Travis does for a living.

As for how serious the romance is, Kourtney and Travis are still playing coy and keeping most of the details under wraps.

Fortunately, like all of her sisters, Kourtney surrounds herself with loose-lipped sycophants who are more than happy to talk to the press.

'It's been very low-key," an insider told E! News in January.

"They are a really good match, and Kourtney's entire family already loves Travis. They have been neighbors and great friends for years, and it just recently turned romantic."

Kourtney and Travis have know each other for years, having run in the same SoCal social circles.

But it wasn't until this year that they decided to take their relationship to the next level.

"The chemistry and flirtation has always been there," the source said about Kourtney and Travis.

"They have a lot in common, and Kourtney has always been attracted to how Travis is as a parent. He's an amazing, hands-on dad, and Kourtney loves that about him," the insider continued.

"They love relaxing at home with their kids, and everyone gets along. It's going well, and they aren't putting pressure on it being super serious at this point."

Well, there you have it.

Their aesthetics might serve as a constant reminder of their very different upbringings, but there are more important things than the past.

Travis is said to be a remarkable committed father, and with three kids of her own, Kourtney is probably smitten by his dad skills.

Folks, the odds were against them in the beginning, but these two might actually make it.
