Star with a heart! Justin Bieber grants wish of four-year-old girl fighting cancer with backstage meeting

Justin Bieber made a dream come true for one cancer-stricken little girl.
The 18-year-old pop star invited four-year-old Hailey Roser to meet him backstage at his Milwaukee, Wisconsin concert on Sunday night.
The tot is a huge fan of Justin's and had been longing to meet him and it took a huge social media movement to make it happen.

 

Dream come true: Justin Bieber made four-year-old Hailey Roser a believer after meeting her backstage at his Milwaukee concert Sunday night. Hailey was diagnosed with brain cancer last August

After Hailey was diagnosed with brain cancer last August, her parents began a campaign on Twitter and Facebook to get their daughter a meeting with the young singer, with one of the campaigners even calling TMZ Live for help to realize the dream.
The 'Healing Hailey' movement was then brought to the attention of Justin's manager Scooter Braun and a five-minute chat was arranged.
Hailey has been going through chemotherapy treatments and had to get her doctor's consent before making the trip to attend Justin's show.

 

 

You call, he listens: Justin, seen here performing on October 20, enjoyed his chat with little Hailey, which started with her parents' campaign on Twitter and Facebook
