American Idol Alum Scares as Creepy Clown at Great Adventure

'American Idol' darling Jax from East Brunswick, New Jersey scared some unsuspecting thrill seekers at Six Flags Great Adventure Saturday night during Fright Fest.

According to NJ.com,

Six Flags spokeswoman Kristin Siebeneicher said the singer's manager reached out to the theme park to see if it would be interested in having Jax be a zombie for a night as part of Halloween weekend.

"We were psyched, we thought is was a fantastic idea," said Siebeneicher, adding Six Flags was asked not to promote her appearance in advance. "They wanted her to have the best opportunity to get out there authentically scare people and that's what's Fright Fest is all about, so we were happy to honor that request."

And Jax really did freak some people out!
