Megan Piper is an adult film actress who was ready to go to a high-school prom with a student Mike Stone.

The Minnesota teen got so fed up with everyone asking him who he was going to take to prom that he started inviting adult starlets and after sending out more than 600 tweets, Mike received a provisional 'yes' from porn star Megan Piper - on the condition that he paid for her air fare from Los Angeles to Oakdale, Minnesota.

Another adult film star Emy Reyes, also responded to the tweet saying, "Awww that's reappear [sic] hun and I would love tooo."

Mike chose Megan, but the school says no way.

Patty Phillips, superintendent of the North St. Paul-Maplewood-Oakdale School District, said that Piper, 19, would be prohibited from attending the dance because her appearance would be 'inconsistent' with two district policies pertaining to visitors to school buildings and sites, according to Fox News.

The policy states that anyone can be denied entry to those events if the visit is 'not in the best interest' of the district.

The 19-year-old porn star was disappointed about the decision, she acknowledged the school was acting in the best interests of the students.

"I'm not thrilled; I kind of wanted to go, but I understand," Piper said in a telephone interview.

No word yet from Stone on his prom plans.
