Carly Rae Jepsen’s dream Christmas present would be a private performance by Mariah Carey.

The 27-year-old singer’s favourite festive track is legendary diva Mariah's classic single All I Want For Christmas Is You.

"I want Mariah Carey to come to my house and sing All I Want For Christmas Is You," Carly told BBC Radio One. "It's the best Christmas song!"

The Grammy Award-nominated singer is looking forward to some time off from her busy tour schedule over the holiday season.

Carly will get to have a short break from her performances as Justin Bieber's Believe tour support act over Christmas.

She is not good at getting up in the mornings and relies on her team of people to help her function through the day.

"Sometimes it's a pretty early morning. It hurts. Early flights... Every day I'm like, 'I'm not getting up,' and I barricade the door and say, 'I'm not getting up,’" Carly continued.

"[Bieber has two people to get him up?] I have one waking up person, one, though she makes it enticing for me to get out of bed. She shows up with breakfast, a Starbucks and a tap on the door. I'm like a teenager and first I say, 'No,' then I smell the coffee! Being hooked up on a caffeine drip sounds like a good idea. I might have to suggest that."
