Justin Bieber Gears Up for 17th Birthday With Grandparents and Cheesecake!

When you're the hottest teen sensation, what do you plan on doing for your 17th birthday? Well if you're Justin Bieber, you spend it with your grandparents and sweet talk your grandma into making a special dessert!

"Hopefully my grandparents will be out here and I'll be able to spend time, a little bit, with them," the singer tells 'Entertainment Tonight,' which will aired last night. "My grandma makes the best cherry cheesecake. She made that for my 13th birthday."

The teen heartthrob says there will be "no birthday bash" on March 1 when he turns another year older, simply because of the short amount of time he has off from his hectic touring schedule.

"I only have, like, four days, so I'm just going to relax, because I start my world tour," says Bieber. "So just going to mentally prepare and just relax."

Bieber's world tour will launch on March 4. For a complete list of dates where the Biebs will be performing, click here.
