Mark Wahlberg is apparently tired of seeing Justin Bieber's underwear. In a live web chat with U.K. newspaper The Sun, the "2 Guns" star delivered a strong message to the young singer.
"Justin, are you listening? Don't be so naughty, yeah," Wahlberg said with a British accent in the Tuesday webcast. "Be a nice boy, pull your trousers up, make your mum proud, yeah? Stop smoking all that weed, you little b------."
But Wahlberg then showed his true feelings, laughing and saying Bieber should be given some slack.
"He's a kid! Let him live his life," he said, adding: "He's a teenager, obviously living in a different day and age. Everybody's got a cell phone and paparazzi everywhere. I was in prison before I got a record out and I don't think he's been to prison. I don't think he wants to go."
But still, he offered some words of wisdom to the recording artist: "This career can be short-lived — you might as well be the best you can while you're doing it, while you're in the game. And after, if you want to go 'F' off, do that."
It's not the first time a Hollywood star has criticized Bieber's clothing -- or lack thereof.
Olivia Wilde tweeted in March: "Bieber, put your f------ shirt on. (unless you lost all your shirts in a fire in which case my condolences and please purchase a new shirt.)" Following a backlash from Bieber fans, Wilde later said during an appearance on "The Tonight Show" that the comment wasn't meant to be "mean-spirited" but intended with "love."
Meanwhile, Wahlberg in the live webcast said he and Bieber are still talking about doing a movie together. It was previously reported that Wahlberg wanted Bieber to star as a street-hustler basketball player in a movie that Wahlberg once described to E! News as "'The Color of Money,' but in the world of inner-city basketball."
"We have a great script that … could be a vehicle for him to make his debut in movies," Wahlberg told The Sun on Tuesday. "That may happen, then maybe we could do something for the soundtrack."
Bieber has had a roller-coaster year that has included accusations of a hit-and-run with a paparazzo (the L.A. County District Attorney declined to prosecute), drawing fans' anger by showing up late on stage at London's O2 Arena and leaving an ill-advised comment the guestbook of the Anne Frank House in Amsterdam.
Among other headline-making incidents: He was hit with assault charge and speeding accusations, was tackled by a fan, had his tour bus searched for weed, insulted Bill Clinton, saw his monkey confiscated in Germany, had his earnings stolen after a concert in South Africa and was booed at the Billboard Music Awards.
Wahlberg, meanwhile, stars in "2 Guns" opposite Denzel Washington; the movie hit theaters Friday. The actor is currently shooting "Transformers 4."
