LOS ANGELES: Justin Bieber‘s mom is speaking out.Following a list of controversial antics during the last few months by her superstar son, Pattie Mallette admits the 19-year-old is far from perfect. “He knows what I disagree with and he knows all the things that I’m really proud of him for, too,” Mallete says. “I mean, people don’t talk about all the great things he does every day. Every night before a show, he meets with Make-a-Wish kids. He goes to sick kids’ hospitals. He visits with them [and] takes his time. He gives back to charities.–SP
