When it comes to Santa Claus, Justin Bieber was never a “Belieber.” The singer reveals in an interview with AOL Music that his mom, Pattie Mallette, saw to it that her son never believed in the bearded gift giver.

"My mom always told me there wasn't a Santa," he said. "This was her logic: She thought if I grew up knowing about Santa then finding out he wasn't real, that it would be like she was lying to me. And then when she told me about God, I maybe wouldn't believe her."

Bieber, a Christian, cites his mother’s decision to be "straight up and honest with me all the time."

Despite his grown-up understanding of Santa, Justin says he’s no Grinch. "I didn't tell my friends or ruin it for anyone - I was a good kid!" he tells AOL.

The 17-year-old says his holiday plans include heading back to his native Canada to have Christmas Eve dinner with his mom’s family. Then it’s over to dad's house on Christmas Day to hang out with his little siblings, Jazmyn, 3, and Jaxon, 2. “When it comes to my little sister and brother, I spoil them,” says the Biebs.

As for his own Christmas list, Justin admits there’s not much on it. "To be honest, I really don't have any Christmas wishes this year... I just wish to be happy and that everyone be healthy in my family," he says. "And I wish that everybody gets to hear my Christmas album – and hopefully like it!"

He may already have that last one in the bag: Justin’s new album “Under the Mistletoe” is the first Christmas album by a male artist to debut at No. 1 on the charts.
