Mark Wahlberg Offers Justin Bieber Advice

He made plenty of his own mistakes while coming up in the entertainment industry, so Mark Wahlberg is the perfect guy to help Justin Bieber stay on track.

During a web chat with The Sun, the “Fear” actor joked around a bit when asked his opinion of the “Baby” singer.

Speaking in a fake English accent, Mark quipped, "Justin, are you listening? Don't be so naughty, yeah? Be a nice boy, pull your trousers up, make your mum proud, yeah? Stop smoking all that weed, you little bastard."

With a more serious tone, he added, "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, 'You know what, now is the time to be focused and to be disciplined and to be the best that I can be in this career.'"

"He's a teenager living in a different day and age...I was in prison before I got a record out, and I don't think he's been to prison, and I don't think he wants to go. He's a nice enough kid."

“You're going to be a teenager, but if you're being a teenager in the spotlight, then you're going to be criticized for it. This career can be short-lived -- you might as well be the best you can while you're doing it."
