Kourtney Kardashian and Travis Barker are ENGAGED!

It's finally happened. After months of speculation, numerous engagement (and pregnancy) rumors, Kourtney Kardashian and Travis Barker got engaged!

According to reports, the Blink-182 drummer popped the question to the Poosh founder in a romantic sunset beach ceremony in California. A source told E! News that Kourtney "had no idea" the drummer was going to propose at the Rosewood Miramar hotel on Sunday, Oct. 17. 

"It happened during the sunset at Rosewood Miramar," the source shares. "They had just got back from NYC and decided to do a day trip to Montecito. Kourtney thought it was going to be a casual day, as they always go to Rosewood, and she was totally thrown off."

The insider adds that Travis likely chose the popular locale, as "it's one of their favorite places and they have a lot of memories there."

Kourtney Kardashian shared a few snapshots from the special moment to her Instagram, simply captioning the post "forever" and tagging her future husband. Check out the post below.

The source also added that Khloe Kardashian, Kris Jenner, her boyfriend Corey Gamble, Kim Kardashian, and more loved ones witnessed the proposal, adding, "They were all in on it and surprised them afterwards inside the hotel. They are all celebrating in the restaurant and have a private area."

Kim Kardashian posted a sweet video to congratulate her older sister to her Instagram Story and her Twitter account, writing "KRAVIS FOREVER". Check out the sweet video below.
