A source told PEOPLE of the proposal, "It was a very romantic beach proposal at sunset. Travis took Kourtney for a walk, and you could tell that she wasn't sure what was going on when she saw all the roses on the beach. Red and white roses were shaped into a heart. There were a lot of candles. They both looked very happy."

In a recent Health magazine cover story, Khloé Kardashian, responding to a question about whether she goes to different siblings for different things, mentioned that sister Kourtney is "so loved up right now" in her relationship with Barker.

"It depends on the stages that the other siblings are in, in their lives," said Khloé, 37. "For example, Kourtney is so loved up right now, she's probably not the one I'm going to go rave with. You know what I mean?"

Last month, Barker declared he wanted to laugh with Kourtney "for the rest of my life," after she shared a series of memories to Instagram, including a clip of the couple holding hands at a table. The Poosh founder responded, "my whole life."
