Justin Bieber took Mom mom Pattie Mallette to the American Music Awards 2012.

The hunt for a new girlfriend for Justin Bieber is on as former girlfriend Selena Gomez is moving on without Justin and thinks their break-up is healthy.

18-year-old Justin and the beautiful 20-year-old actress recently broke up as Selena gave up on their relationship of almost two years.

Francia Raisa (The Secret Life of the American Teenager) has praised them for their maturity throughout the split.

She told Wetpaint: ''[Selena's] great. They're both adults about the situation and they're still friends. It's probably the healthiest breakup I've ever seen in my life and I wish I was that mature when I was her age.''

Despite the civil break-up, it was recently claimed that Selena's friends hope her romance with Justin is over for good as she has ''shed many tears'' over him in the past year.

A friend of Selena's said: ''It's been so difficult to watch this unfold over the past year or so. Selena has shed so many tears over Justin.

''She's tried to split up with him so many times but they have always ended up back together.

''It's out in the open now and that is one of the toughest parts, so that means there's more chance it will be permanent this time. But we expect Justin to try to win her back - and he tends to get what he wants.''
