AceShowbiz - "CSI: Crime Scene Investigation" star George Eads has lavished praise on Justin Bieber - insisting he has gained a lot of "respect" for the teenage pop star since his cameo appearance in the show.

The singer filmed a guest slot on the crime series last year and recently returned to appear in a second episode. He shot many of his scenes with Eads, and the actor admits he enjoyed working with the "Baby" hitmaker.

Eads tells E! Online, "He's a cool kid. He's in the eye of a hurricane and I think he handles himself really well...We had a lot of intense scenes together. We got along really well. I really respect the kid."

And Eads believes Bieber could have a future acting career as long as he continues to improve his technique, adding: "I think he has a lot to learn, but he was just fine for what he was doing there. You know, it's not Gone With the Wind. It's CSI! It's four or fives lines. I mean, it's not a Rubik's Cube."
