Justin Bieber Pulls April Fools Prank on TMZ

"As promised taking all fan phone calls TODAY at (888) 847 9869," Bieber Tweeted yesterday morning, leaving the phone number for TMZ on his account.

"Talk to u soon!"

From there, millions of Bieber's followed called in to the celebrity gossip website's tip line… which is toll-free and therefore likely cost the company a bit of coin.

Justin eventually deleted the Tweet, but not before the number hung around the Internet for long enough to cause some damage.
