Los Angeles: Pop star-turned-actor Justin Timberlake has praised on his former 'Mickey Mouse Club' co-star Ryan Gosling saying he's one of the finest young actors in Hollywood.

The 'Cry Me a River' hitmaker grew up with Gosling and the two castmates even lived together as their TV careers took off and Timberlake is very proud of his pal's success.

"He's unbelievable; I think one of the best actors of our generation... He is working a lot too. It's hard to keep up with him," he said on a TV show.

Timberlake has very fond memories of hanging out with Gosling when the two pre-teens were on the verge of stardom.    

"His mother had to keep her job in Canada the second year that we were on the television show and my mom was his guardian for, like, six months, so we actually lived together. We were probably a little closer than the rest of the kids that were on the show just because we had to share a bathroom," Timberlake said.

"We used to do terrible things. We thought we were so cool when we were on the Mickey Mouse Club. Looking back on them, they weren't as bad as I thought they were at the time.

We stole a golf cart. And we we're like, 'Yeah, man. We're stealing a golf cart...' but... it's, like, on a backlot; there's golf carts everywhere.

"We stole the golf cart and we drove into Mgm Studios, which is totally illegal by the way... We went and got milkshakes," he added.
