Happy 18th Birthday, Justin Bieber!
Justin Bieber turns 18 today! To celebrate the milestone, the teen pop sensation stopped by The Ellen DeGeneres Show, where his manager presented him with an eco-friendly Fisker Karma car. Bieber's reaction: "That's mine? That's amazing!" He then took to Twitter to ask his fans to give back by donating to Charity: Water, a nonprofit organization that provides clean drinking water to people in developing nations. "I want to use my bday to help others. if u want please donate $18 to @charitywater on my 18th bday!" he wrote. Beliebers, leave your birthday wishes in the comments!
