There wasn't actually a sign saying "No boys allowed" posted on the doors of Nassau Veterans Memorial Coliseum Saturday, but it sure seemed like it was girls only at the first Pop-Con.
Though the lineup for the tweeny-popper concert featured Selena Gomez, Sean Kingston and Long Island band Push Play, all those girls made it clear who the star attraction was.
"Justin Bieber! I'm in love with him. I would do anything for him. He's the only one," said Lauren Miller, 14.
She wasn't the only one declaring her love for the 15-year-old tween idol.
"He's cute. He sings good. He's absolutely amazing," said 13-year-old Gabrielle Wusyk, who, like many in attendance, was wearing her heart on the short sleeve of a Justin Bieber T-shirt. Not that it kept her from waiting in line to shell out $30 for another shirt.
In fact, amid the sounds of screaming tweens as opening acts like Joey Page and the Wonder Girls performed, the sound of "ka-ching" came through loud and clear from concession stands selling clothing, posters, CDs and other pop-aphrenalia.
"Business has been good. I think things haven't really changed much as far as concerts. People are still willing to pay $30 for a T-shirt and $80 for tickets. We don't even make the prices. The bands know it's going to sell. It's pretty wild," said Bill Gunther, who was working a booth with Selena Gomez programs.
Some kids, like Barbara Dalia, came with their own goodies. The 11-year-old brought three posters, which she had hand-drawn and decorated with photos of Bieber, that she hoped to deliver in person. When asked what she was looking forward to, she just said "Hugging him."
In November, "we went to the Roosevelt Field thing and we were very disappointed that we didn't get to see him, so that's why we're here," said her mother, Corinne Dalia.
For Dalia and other parents who showed up for the start of Pop-Con at 2 p.m., it was going to be a long wait: Bieber wouldn't take the stage until 7:15.
"I thought it was going to be three hours. When I bought the tickets online, it just had the three performers on there - Justin Bieber, Selena Gomez and Sean Kingston," said Maria Vecchione, who purchased the tickets as a 13th birthday gift for her daughter, Rayana. "I didn't know it was a whole bunch of performers who were going to be here. I had to change my plans for tonight. I was supposed to go out to dinner."
Tom Wusyk, Gabrielle's father, also ended up having a longer day than expected. "When I bought the tickets. I didn't realize it was six hours or I wouldn't have called the radio station," he said.
