Justin Bieber sings Happy Birthday for Twitter's 10th anniversary

Celebs celebrate the social media platform’s anniversary

Posted on


Twitter celebrated its 10th anniversary on Monday, and a star-studded roster of celebrities wished the social media platform happy birthday using the hashtag du jour: #LoveTwitter.

Not every celebrity went to the lengths Justin Bieber did, though. He was thanked by the main Twitter account “for sharing #Purpose with us.”

The 22-year-old sang “Happy Birthday” in a put-on voice deeper than his usual tone.
