Justin Bieber's Family: He Doesn't Need Rehab
Justin Bieber's grandmother has denied the teenager needs to enter rehab following an eventful 2013.
Diane Dale, who was among several of the singer's family to attend the premiere of his new film in Los Angeles, said the media had been "terrible" to him as he travelled the world on his global tour.
"There are so many lies going around," she said. "A little bit is true but most of it is lies. It's terrible."
The 19-year-old's grandfather Bruce Dale added: "He's still a teenager growing up in the spotlight.
"How would you like to wake up in the morning with a camera shoved in your face? I don't blame him for acting out. I would."
A string of peculiar moments on Bieber's world tour began in London, where he turned up late for one concert, collapsed on stage at another and lunged at a photographer.
In March, he was spotted strolling topless in temperatures of -10C at an airport in Poland, before his pet monkey Mally was seized at a terminal in Germany after he failed to produce the correct paperwork.
The following month, police in Sweden said they found drugs and a stun gun on Bieber's tour bus, while in May, a fan grabbed him on stage as he performed in Dubai.
He was hit by a bottle and walked off stage during a gig in Brazil in November, before kicking the Argentine flag at a concert in Buenos Aires and allegedly spray-painting the wall of a hotel in Australia.
The Canadian star split with his girlfriend Selena Gomez in January, and a paparazzo was killed taking pictures of his sports car in the same month.
Speaking at the premiere, Bieber's mother Pattie Mallette defended her son, saying: "It's tough because the whole world is a critic.
"I think sometimes people dehumanise celebrities and I think what's so great about this movie is that you get to see his humanity, the really sensitive side."
Jon Chu, who directed the film and took charge of Bieber's first feature, said the singer had "always been a troublemaker" but described him as "charming" and a "good kid".
"I wouldn't come back if I didn't like him and who he was," he added.
Justin Bieber's Believe is released in cinemas in the UK on December 26.
