Not only is Justin Bieber being very charitable on his 17th birthday today (March 1), the pop singer tells SiriusXM's The Morning Mash Up how he wants to spend the momentous occasion.

"Probably just going to chill for my birthday," Bieber says. "No party or anything. I just want to relax. I have four days off, I want to chill."
 
And we're sure his mom didn't take it personally when the show's co-host asked him if his mother is cooking up something special for his birthday.
 
"No, my Mom doesn't cook," he says. "She's awful at cooking. She's awful, awful, awful at cooking. But, my Grandma cooks...hopefully she makes me cheesecake for my birthday."

We're sure his mom, who pretty much keeps her son's busy schedule too, could use the day off! Happy Bieber day!
