Mark Wahlberg has built an entire career on his reputation as a Hollywood tough guy, but if it were up to him, other kids wouldn't take the same road he's been down.

In a web chat with UK paper The Sun, the Two Guns star revealed his advice for young Hollywood — and he had one speed-limit ignoring, bucket-peeing Canadian in particular in his sights. 

Mark offered some wise words for Justin Bieber regarding his recent media snafus, telling the interviewer, "He's a teenager. Obviously he's living in a different day and age where everybody's got a cell phone and paparazzi's everywhere. But, I was in prison before I got a record out. I don't think he's been to prison, and I don't think he wants to go."

Then, switching into parent mode for a moment, Mark jokingly gave the star some advice. "Justin, are you listening? Don't be so naughty. Be a nice boy. Pull your trousers up. Make your mum proud. Stop smoking all that weed, you little bastard."

Mark then reverted into his regular form, saying, "No, look, he's a kid! Let him live his life! I would hope that he would look at it like I wish I looked at it, and think now is the time to be focused and to be disciplined and to try to be the best that I can be at what I do in his career, like an athlete should."

Mark also revealed that the pair's movie project, which had been discussed earlier in the year, may still be in the works — you know, if Justin's gotten his act together by then.
