Justin Bieber turns the big 18 tomorrow and we're all excited! Now that The Biebs is officially legal, we must celebrate! In this 'Hot Minute' dedicated to Justin's big day -- I want to show you a cool video that Google Chrome made for Bieber, which chronicles his impressive reach and presence on both Google and YouTube! As a gift, the pop star's Bieber Fever stricken fans will try to break the Guinness World Records' mark for most social media messages sent in a 24-hour period. Happy BDay!
