The 19-year-old model's relationship with the singer is believed to have turned romantic in recent weeks, reported People magazine.
Asked if he approves of Bieber dating his daughter, he said, "Absolutely - but there's no label on it, just friends. Mr Bieber is a wonderful young man, hugely talented, got a lot more success ahead of him."
And the 49-year-old actor insisted the couple are "far away" from being at a point where they consider marriage.
