Meanwhile, Justin also recently reconnected with his mum after four years of estrangement. Pattie came to his defence after Selena's mum publicly slammed her decision to get back with the Biebs, and posted a gushing post alongside a snap of them cuddled up on a boat. "I’m so proud of the amazing young man you are, and the young man you are becoming," she wrote.

"I admire your character and integrity. You are maturing beautifully and wise beyond your years. You are so funny that I find myself laughing out loud when I’m alone, remembering of something you said or did. " (Image: Instagram) She finished: "And your heart is gold. I love you to the moon and back. Ps. Did I mention I was proud of you?" Justin and his mum barely spoke for two years, with the star telling Billboard in 2015 that their relationship was “pretty nonexisting. I was distant because I was ashamed. I never wanted my mom to be disappointed in me and I knew she was. "We spent some time not talking, so it takes time to rebuild that trust … it’s hard, but getting better. She’s an amazing woman and I love her.” Pattie's post came after Selena's mum Mandy Teefey told Gossip Cop that she's "not happy" about her daughter rekindling her romance with Justin, though added, "Selena can live her life however she wants as long as she is happy, safe and healthy."<doc-sep>
