Justin Bieber accidentally reactivates Instagram account

Pop star Justin Bieber says his brief return to the photo-and-video-sharing site Instagram was accidental.

Two weeks after quitting the site, the Canadian singer briefly returned to it on Monday.

Bieber later took to Twitter to explaining that he never meant to reactivate his Instagram account.

"Still no Instagram it was an accident," he wrote.

Bieber left the social media earlier this month after his relationship with Sofia Richie caused a lot of drama.

The "What Do You Mean?" singer first threatened to make his account private while asking fans to stop posting nasty comments about his rumored new girlfriend.
