The rapper - who topped the Billboard charts with his 1990 hit 'Ice Ice Baby' - told Access Hollywood Live that he is very impressed by Bieber finding success at such a young age.

"I see similarities, I definitely see similarities," Vanilla Ice said of Bieber. "He's a great guy. He's doing great out there right now."
Bieber has recently been at the centre of scandals for allegedly being photographed holding a marijuana cigarette and also for a photograph that appears to show him groping a female fan.
Vanilla Ice addressed Bieber's recent troubles in his television interview, saying: "Let's hope that it doesn't train wreck, you know, because I had a weekend that lasted a few years and you have to figure out your purpose in life after you're through with your artificial life of being on stage and all the glamour and everything.
"There's a real life in there and then you have to do that while growing up... So there's going to be some growing pains and everybody is going to be watching. It's going to be entertaining!"
Like Vanilla Ice, Bieber has explored hip hop under the guise of rap persona Shawty Mane.
Bieber's most recent album Believe: Acoustic was released last week.
