Justin Bieber is NO JOKE in the skateboarding world -- in fact, he's BETTER than Lil Wayne ... so says pro skater Terry Kennedy.
Terry knows what the hell he's talking about -- he was the captain of Pharrell's Ice Cream skateboarding team when he was a teenager.
And Kennedy says he didn't need to see the recent footage of Bieber skating at Venice Beach to know the pop star's got skills.
"Rob Dyrdek has skated with him. I've skated with him ... he's respected," Kennedy says.
Look, Kennedy isn't saying he's the greatest skater ever -- "he's ok" -- but says he was genuinely impressed with JB's talent.
But who's the BEST celebrity skater? Kennedy's naming names. Check out the clip.
