Pulling a Leonardo DiCaprio, are we? And are those stains on his white tee? Someone get this boy a Tide pen!

On Friday Justin Bieber went to a lunch meeting in Beverly Hills, and though he wasn't in the mood to be photographed, we still got a peek at his tatted guns. Loves it!

Earlier this week the pop star announced that his new single, "What Do You Mean," would be released later this month, and he explained the meaning behind it to pal Ryan Seacrest. “Well, girls are often just flip-floppy,” Justin said. “They say something and they mean something else. So … what do you mean? I don’t really know, that’s why I’m asking.”

“I’ve been working a lot in the studio, just trying to have a consistent sound, a cohesive sound,” the pop superstar continued. “I get in my head a lot and I get kind of depressed because I want it to work so badly. I want people to love it. I want to inspire people. Sometimes I wonder, ‘Is this good enough? Is this the direction I want to go?’ I had kind of a rough week last week. I get in my head and I don’t want to get out of bed sometimes.” Aww! We're sure we'll love it -- and we can't wait to see if it pays homage to his ex, Selena Gomez!
