Justin Bieber's grandparents Bruce and Diane Dale couldn't have seemed more proud as they walked the purple carpet at the Hollywood premiere of Believe last night. But hundreds of miles away in Canada, it was just another weeknight for his paternal grandparents, George and Kathy Bieber. All but abandoned by their superstar grandson, they sometimes feel "he doesn't care," George has said. And some days, they barely recognize the man he has become.

Reached at his home in Mitchell, Ontario, George admitted that he would have liked to have attended the premiere in L.A. -- if he had been invited. As for his relationship with Justin, George sighed heavily before answering, "I really don't want to talk about it."

Just months ago, George potentially ended all hope for a relationship with his wayward grandson when he spoke out to bash his bad behavior.
