Miss Delaware Teen USA has resigned Tuesday after a video surfaced online that allegedly features the 18-year-old beauty queen engaging in a sexual act.

But she says the woman in the video wasn’t her.

A rep for the pageant confirmed Melissa King’s resignation to TMZ, stating: "I would like to confirm the Miss Delaware Teen USA pageant has received a resignation letter from Miss King’s attorney."

King spoke to a Delaware news site and denied that she is the one featured in the sexually explicit video, posted on an adult website.

She told Delaware Online that she was aware that reports were claiming she was the woman in the video.

“There are comments saying this, however, it’s not comments that are true,” she said.

A rep for the pageant said the Miss Delaware Teen USA runner up would take King’s place.

The voice mail message for the Miss Delaware Teen USA office stated the office is currently on winter break. A rep for the pageant did not return FOX 411's email request for comment.

King's lawyer also did not return our calls.
