Miss Delaware Teen USA has given up her crown Tuesday after allegations surfaced that she starred in a porn.

Melissa King, 18, resigned the day after a porn website posted a video that claimed to feature the 2013 beauty queen.

"I would like to confirm to you that the Miss Delaware Teen USA pageant has received a resignation letter from Miss King's attorney," Dara Busch, pageant spokeswoman, wrote in an e-mail to the News Journal in Delaware.

The woman in the porn looks like King and admits to a man off-camera that she has competed in beauty pageants.

But when contacted by the newspaper, King denied it was her in the clip, which is on YouTube.

On Tuesday night, @Melissa_M_King retweeted on Twitter, "If a good person does a bad thing, it does not make them bad."

The runner-up, Hailey Lawler, will take King's place, officials said.

Miss Delaware Teen USA is operated by the Miss Universe Organization.
