Joe Jonas and Brenda Song are 2 teenager stars in the Disney Channel. According to this article, Joe, who wore a bright pink t-shirt under his black leather jacket during the outing, was seen making his way out of the sushi joint all alone and quickly heading to his parked vehicle. Once the middle of Jonas Brothers got into his ride, Brenda was videotaped making her way to his car.
In my opinion, hanging out or having a dinner between 2 friends is very usual. It's just because they are popular, so paparazzi always try to get information about their private lifes. I bet a lot of stars feel very annoyed about that.
