The 20-year-old actress had stopped to sign autographs for the pair outside an MTV taping in Manhattan, and agreed to hug them both for the snap. However, Hudgens was left scared after they began passionately kissing her.
"It was these two girls in their mid 20s with tattoos and stuff. So they give me a hug and suddenly, I feel someone kissing my neck and this girl was making out with me, my neck!" Contactmusic quoted her as having told the New York Daily News.
"I was like 'oh my God!' and I ran away as fast as I could. That's my craziest fan story," she added.
