There is no arguing with pop sensation Justin Bieber — and that goes for his mom, too! In Touch has learned that Justin put his foot down when his mother, Pattie Mallette, wanted to use a picture of her famous son on the cover of her 2012 book, Nowhere But Up: The Story of Justin Bieber’s Mom, to draw sales. “When Justin found out, he refused to go along with it, and they had a series of arguments,” Marc Shapiro, the author of Legally Bieber: Justin Bieber at 18, dishes to the new issue of In Touch, on newsstands now. Marc adds that one night the fighting became so intense that Justin’s longtime manager, Scooter Braun, was forced to step in and plead with the 19-year-old pop star to let it go. “Ultimately, Justin compromised and agreed to a couple of press interviews with Pattie,” the author tells In Touch. “But he was upset.” Despite the hard feelings, Justin reluctantly penned a foreword for Pattie’s memoir — and now all is forgiven. “To see it on paper meant a lot to me,” says Pattie. “I melted.” For more, pick up this week’s issue of In Touch, on newsstands now.
