The Blink-182 drummer is officially keeping up with the Kardashians!
Kourtney Kardashian and Travis Barker got engaged with a romantic, beachside proposal on Sunday in Montecito, Calif. He popped the question at sunset surrounded by candles and roses in the shape of a heart.
"It was a complete surprise for Kourtney. Travis told her family that he planned to propose, but everyone was great at keeping it secret. The Rosewood is their favorite for short weekend getaways. They often stay at the hotel. This is why Travis proposed there. It's a very special place to them, but it was also easier to keep everything a secret by proposing there," a family friend reveals to PEOPLE.
