LOS ANGELES, Calif. -- Teen singing sensation Justin Bieber says there's one girl in particular that makes him nervous enough to shake in his kicks! The 16-year-old Canadian star told Seventeen magazine - in a special all-Biebs collector issue on newsstands June 15 - that he's usually pretty calm around the opposite sex, except for one exceptional woman. "Sometimes, but not really," he said of getting anxious around the ladies. "I did get nervous when I met Beyonce. I was shaking! I was afraid I'd say something stupid. But she calmed me down. She's awesome." When it comes to his own someone special, Justin said he's looking for a girl he can laugh with. "I like someone who's funny, confident, and not afraid to be herself," he told the mag. According to Justin, there's no shortage of females who will go to great lengths to get close to him. "Man, there are so many [wild fan experiences]," he continued. "The incident in Long Island was pretty crazy with the fans shutting down the mall and me not being able to show up. When I was in Seattle, this girl came out of nowhere and she tried to hug me, but she tackled me instead. It was really scary." Beyond tackling, the "Baby' singer said his fans are even getting their moms involved in the Bieber mania. "Then there was another girl -- in Miami -- who's Mom got a tattoo [of a DJ's face on her back] so her daughter could get meet-and-greet passes to see me," he recalled. "It's all so wild!"
