Mark Wahlberg has been where Justin Bieber is at now.
The Oscar nominee was once a teenage star and, in light of Bieber's impressive run of scandals and moronic behavior (peeing in a bucket? Really?!?), Wahlberg has some advice for the young celebrity.
"Justin, are you listening? Don't be so naughty, yeah?" Wahlberg joked in a Webchat with Great Britain's The Sun. "Be a nice boy, pull your trousers up, make your mum proud, yeah? Stop smoking all that weed, you little bastard."
The actor was mostly kidding, however, though he did then get serious and jump to Justin's defense.
"He's a kid. Let him live his life," Wahlberg said. "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."
Wahlberg actually served time in prison prior to releasing his first album, something Bieber has been fortunate to avoid so far.
"He's a teenager living in a different day and age," said the 2 Guns star, adding that the artist should realize his career may be "short-lived" and he should work as hard as possible on it, before concluding simply: "He's a nice enough kid."
Bieber and his entourage are under investigation for a brawl that broke out this weekend a few blocks away from a Hamptons nightclub.
