Snoop Dogg's VMA Award Mantel: His Cadillac

NEW YORK (CBS) The MTV Video Music Awards aren't until Sunday, but Snoop Dogg already knows where his Moonman trophy will go if he wins: on the roof of his car.

"Right on my Cadillac," he told CBSNews.com on Tuesday.

The rapper is a double nominee heading into the awards - his collaboration with Katy Perry, "California Gurls," is nominated in both the Best Female Video and Best Pop Video categories.

Working with Perry on the song and video was "a treat," he said.

"She was really fun, she was exciting," he added. "[The song] was her direction...Once I got the direction from her, I went and did my thing and she was happy with it."

The star (whose real name is Cordozar Calvin Broadus) is also lending his voice to a cause close to his heart, with some help from 7-Eleven's "Coffee Cup with a Cause" program. A custom coffee cup that he designed will be sold in stores, and the proceeds will benefit the Snoop Youth Football League, which he founded in 2004.

The league serves children between the ages of 5 and 13, teaching them the value of teamwork, sportsmanship and the importance of academics. More than 3,500 kids have gone through the SYFL since the league started six years ago - something the rap star said "feels great."

"Some of those kids are in college now, some are in high school now," he said. "They're getting a new breath of fresh air, a new life."

He explained that his affinity for football stems from his personal experience playing the sport when he was young.

"Great players, great coaches," he said. "That's why I'm so attached to football, and I want to continue doing it."

Balancing his charity work and his family (he's a father of three) with his music career isn't hard, according to the star - in fact, the two coincide.

"It comes hand in hand...It's cool but the charity and volunteer work means more to me because I can give somebody some hope," he said.

When asked if he was working on any new projects, he replied that he is "just staying on the ball right now, trying to stay committed." But when asked with whom he'd like to collaborate, he mentioned BB King and Sade. He also mentioned he'd like to get in the studio with Susan Boyle.

Some of his songs are part of a new collaboration - last week, he became the first rap artist to be featured in the "Rock Band" video game.

How does he feel about his songs being included alongside ones from Jimi Hendrix, The Who, AC/DC, Green Day and other rock greats?

"It makes me feel like a rock star," he said. "It makes me feel like a f--king rock star."
