Singer Justin Bieber is on a "spiritual mission". The 22-year-old singer had "an epiphany" recently, which led him to believe that he needs to reconnect with religion and nature. During days off from his "Purpose" world tour, he has been spotted meditating in parks and enjoying some solo strolls.

"He believes nature and religion - not concert venues and nightclubs - should become his life priorities," said a source. Meanwhile, Bieber recently upset fans when he declared that he will no longer take pictures with them because it makes him feel like a "zoo animal".
