File this one under the “odd sports news” section. A new report suggests that Andy San Dimas, a porn star, was ejected from a Pittsburgh Pirates game at PNC Park for “sexy dancing”—and for wearing a unicorn mask.

The alleged incident took place at PNC Park during a July 13 game between the Pirates and the New York Mets, Deadspin exclusively reports. A Pirates fan identified only as “Dave” provided a rundown of the events that led to San Dimas’ ejection from the stadium, which apparently involved the porn star’s decision to wear a unicorn mask.

According to “Dave,” San Dimas, described as “the girl with the unicorn mask,” told a group of Pirates fans that she was in Pittsburgh to dance at a local gentleman’s club, Deadspin reports. San Dimas, who allegedly described herself as a “major triple x star,” is reportedly a member of the “unicorn army,” a group whose members “take pictures of themselves wearing the unicorn mask in various places.”

At some point during the game, “Dave,” along with other Pirates fans, allegedly convinced San Dimas to don the unicorn mask and dance, in order to attract the attention of a PNC Park camera man, Deadspin reports. “She was doing her sexy stripper dance, but keeping her clothes on,” Dave told Deadspin. When an usher asked San Dimas to stop dancing, she reportedly ignored him.

Eventually, a security guard motioned for San Dimas to “come talk to him” regarding the dance and unicorn mask, but the 26-year-old porn star decided to eject herself from PNC Park instead, Deadspin reports. “Oh I’m sorry I was trying to have a good time at the f---ing Pirates game,” she reportedly told security. “Dave” added that San Dimas’ alleged “glassy eyes” caused some Pirates fans to think that “she was on heroin.”

Although San Dimas hasn’t addressed her alleged ejection from PNC Park on her Twitter feed, she did retweet a friend’s post that seems to confirm that she attended a Pirates game on July 13. Besides her career as a porn star, San Dimas recently had a small part in the 2011 feature film “Drive,” which starred Ryan Gosling.
