E! News reports that Caillat and Young have been together for several years, and he is also the guitarist in her band.

Since dating Young, Caillat has been very vocal about her feelings for him.

Back in 2011, Caillat told Us Weekly that she and Young have a lot in common and work seamlessly together.

"We have everything in common. He helps me with my music and guitar-playing, and we warm up together," she said. "We go everywhere together. It is like having your best friend with you, so I really love it.

Caillat also predicted that she and Young would get married one day.

"I don't think there is ever a rush. If he proposed I would be very excited and I would be happy." she said.

Caillat and Young have yet to announce the date for their wedding.
