India, June 27 -- Justin Bieber has once again caught fans off guard. This time, it is not a new song or album, but a change to his Instagram name.

The 31-year-old pop star is now going by @lilbieber on Instagram. He quietly made the switch on Thursday by replacing the handle @justinbieber that he had used for years.

Fans were quick to notice the update, even though Bieber did not say anything about it directly.

The baby singer dropped a clue regarding the name change earlier in the week. On Tuesday, the star posted some sweet black-and-white photos of himself with his 10-month-old son, Jack, whom he shares with his wife Hailey Bieber.

He simply captioned the post "lil bieber" along with a lock emoji.
