(PHILADELPHIA) -- Smiling on stage at the Miss Delaware Teen USA pageant, Melissa King appeared to be the ultimate girl next door, but she may have actually been hiding a racy past that includes an alleged performance in an adult film and two warrants out for her arrest.

King, a gymnast and freshman at the College of Philadelphia, who said she wanted to work at a fashion magazine after finishing her studies, wowed the crowd and judges, taking home the crown and landing a spot at the Miss Teen USA pageant.

But the teen has resigned her position after a video surfaced online possibly featuring King in sexually explicit scenes. On another part of the video, she tells an off-camera interviewer that she participates in beauty pageants.

King has denied that it’s her in the adult film, but on Feb. 26 she resigned her position, leaving many people to wonder if she’s been living a lie.

On Monday the producers of the video released additional footage of what appears to be King reading a release form out loud, prior to the adult video shoot in May.

“I, Melissa King, am doing this … scene of my own free will and I am of sound mind and body,” King says on tape.

King is also wanted by police in Maryland on two outstanding warrants from 2012, including possession of alcohol by a minor and theft — charges she apparently never revealed to pageant officials. The Ocean City, Md., police department told ABC News that it hopes King will surrender herself and “take care of her outstanding legal issues.”

“We live in an extraordinarily transparent world, and it’s very naïve to think that you’re going to do something as public and not have it show up again,” said Howard Bragman, ABC News consultant and vice chairman of Reputation.com.

King has refused to comment to ABC News. But now many wonder if the girl next door was someone else entirely behind closed doors.
