In just a few days time, Justin Bieber will celebrate his 17th birthday and how does one of the world's biggest music stars plan to celebrate?

In an interview with Entertainment Tonight, the One Time star revealed that he only has a few days to himself before embarking on his world tour.

He said: "I only have, like, four days, so I'm just going to relax, because I start my world tour on March 4, so [I'm] just going to mentally prepare and just relax.

"No birthday bash... Hopefully my grandparents will be out here and I'll be able to spend time, a little bit, with them. My grandma makes the best cheesecake, cherry cheesecake. She made it for my 13th birthday."
