The Canadian pop star took the lucky girls for ice-cream and then treated them to a private concert as he rehearsed for his performance on 'Oprah Winfrey Show'.
Justin Bieber teamed up with Oprah Winfrey to wow three young sisters who missed out on seeing their pop idol in concert when their father was sent to serve in Iraq. 'Operation Justin Bieber' cameras captured the three girls chatting to their dad via Skype.
He told them they were going to Chicago, Illinois to meet Bieber on Oprah. The stunned girls screamed, sobbed and danced around the room, yelling, "Thank you daddy!" Their meeting with Bieber took a twist when they arrived in the city on Monday, May 10 - the pop star was sitting in the front seat of the limousine, which came to pick the girls up.
The singer took the lucky girls for ice-cream and then treated them to a private concert as he rehearsed for his performance on Oprah. There was one more treat in store - the girls' soldier father appeared via Skype on the show and thanked Winfrey for making him "father of the year".
Bieber then added, "When you get back we're gonna have five tickets waiting for you and your family to come to my concert."
