This song is sugary sweet and the video is shaping up to be even sweeter.

Caillat and Young play a couple struggling with the changes in their relationship in the backdrop of a gorgeous house and an equally beautiful country landscape.

The former lead guitarist and back-up singer jokingly says since he's gone solo, his own relationship with Caillat has changed: "We're frenemies."

But in all seriousness, she is actually incredibly supportive and says:

"I think it's good that's he's going to be on his own tour and playing his songs."
