The former "X Factor" judge is "really happy" in her new romance and they enjoy simple things such as eating take-out at her Los Angeles home and "enjoying each others company."

The source added: "Everything is still very fresh but they have been being low-key hanging out."

The "Sober" hitmaker revealed her new romance on Instagram on Wednesday.

Alongside a picture which featured Austin placing a kiss on Demi's cheek, she simply wrote: "My [heart emoji] (sic)"

And Austin also added fuel to romance rumours when he uploaded a different picture of the pair to his own page, which he captioned: "My love," alongside a smiley face emoji surrounded by hearts.

The relationship comes after Demi recently called time on her short lived romance with "Bachelorette" star Mike Johnson.

The couple had enjoyed a string of dates in September, but love between them "fizzled out", partly due to their conflicting schedules.

A source said at the time of their split in October: "Mike and Demi have pumped the brakes. They went on a couple of dates and texted each other every day, but it was never a serious, full-blown relationship by any means. There is absolutely no love lost between them. The timing just wasn't right because they're both so busy."
