"Mark 'Marky Mark' Wahlberg shot his campaign in 1992 and we're still talking about it today, so I hope my ads make an impact the way his have," Justin Bieber told Us Weekly. "I hope his reaction is a positive one."

The "Girlfriend" singer has not spoken with the Oscar-nominated actor about the ads, but Justin knows that there will certainly be comparisons to the 1992 shoot and his own.

"I really hope people will see that I put my own spin on things," he said. "I wasn't nervous about doing the campaign. It was the most fun I have ever had on a shoot."
