Justin Bieber has made Justin Bieber history. His totally unavoidable and completely addictive comeback single "What Do You Mean?" has debuted at No. 1 on the Billboard Hot 100, the first time he's done so in his career. That's right, folks. Even "Baby" wasn't good enough to grab the illustrious spot.

It also means he's knocked the Weeknd's "Can't Feel My Face" down after two nonconsecutive weeks on top of the chart. "What Do You Mean?" sold 337,000 downloads in its first week. Go, Biebs!

Bieber thanked his fans with an adorable Instagram video (see above). "Looks like we did it!" he starts the video. "I want to say we did it again but it's my first number one so thank you you guys. You guys are the best!"
