Did Justin show up to Jessica Jarrell's B'day bash?

Popstar! had a blast at Jessica Jarell's Sweet 16 rollerskating party sponsored by Pastry at Moonlight Rollerway! And yes, the rumor that the Biebs attended with Selena Gomez is true! They showed up later skipping the press line, but posed for sweet pix with the birthday girl. "He's funny, he's a prankster- he's really down to earth!" Jessica tells Popstar! exclusively of her special guest Mr. Bieber!
