Mark Wahlberg has some stern words of wisdom for Justin Bieber. During a web chat with The Sun newspaper, the former child star and "2 Guns" actor gave some fatherly advice to the "Boyfriend" singer, the Huffington Post reports.

"Justin are you listening?" he jokingly said. "Don't be so naughty, yeah? Be a nice boy, pull your trousers up, make your mom proud, and stop smoking weed, you little bastard."

Wahlberg was referring to Bieber's recent behavior that has constantly been landing him in the news. The actor did offer some advice to the 19-year-old pop star defending some of his antics.

"He's a teenager living in a different day and age," Wahlberg said. "I was in prison before I got a record out and I don't think he's been to prison."

"He's a nice enough kid and you're going to be a teenager. But if you're being a teen in the spotlight you're going to be criticized for it," he added.

The singer's bad boy image has been landing him in the headlines time and time again. Most recently, he was involved in a bloody fight in the Hamptons. According to the New York Daily News, the singer's body guards had to "hold him back" during the early morning fight.

The newspaper reports that Bieber went to the club to "pick up girls" and left with two cocktail waitresses who he reportedly took back to his hotel. As soon as the ladies got to the room, he allegedly made them sign confidentiality agreements.

The details of the fight of the fight are a little iffy. The New York Post reports that the "Beauty and the Beat" singer was on his best behavior while the Daily News claims sources said that the "Baby" singer "went nuts" and "was screaming" after he got into an argument with a man when his female companion tried to talk to the singer.

The fight spilled out into the parking lot where Bieber was put into his car by his body guards but he jumped out after someone threw a rock at his window. He reportedly then climbed onto the roof of the car but his body guards took him down. The entire thing was caught on film because camera crews happened to be at the club filming a documentary.
