In hopes of building a better relationship, Justin Bieber admitted to his on-and-off girlfriend Selena Gomez that he needs to work on his maturity.

To prove himself Bieber has been working overtime to show his humility, and “they want to make sure that if they get back together they can do it right,” according to a source.

“He may not realize this, but just admitting that he has growing up to do is a sure sign of maturity," the insider added.

The Boyfriend singer has been working on his behavior since his reunion with Gomez. During his concert in Turkey on May 2, Bieber stopped twice during the show to acknowledge the Azan, an Islamic call to prayer observed five times a day.

One fan posted:

This gesture came a few weeks after Bieber angered fans by writing in the Anne Frank House guestbook, “Anne was a great girl. Hopefully she would have been a belieber,”

He wrote the message while visiting the Anne Frank House in Amsterdam and some thought the note seemed inappropriate and selfish.
