Singer is taken into custody after authorities find hashish and marijuana on her tour bus.

Fiona Apple reportedly was arrested Wednesday at a border stop in Sierra Blanca, Texas, after authorities claim they found hashish and a small amount of marijuana on her tour bus.

Apple, who's currently on tour in support of her The Idler Wheel ... album, was charged with possession and is currently being held at the Hudspeth County Jail, TMZ is reporting.

Apple is scheduled to perform Thursday night (September 20) in Austin, Texas, though it's not known if she'll be forced to cancel the concert due to her arrest. A rep for the singer could not be reached for comment by press time, and an email sent to the Hudspeth County Sheriff's public information officer has yet to be responded to.

In their report, TMZ — which also posted Apple's mugshot — noted that she's not the first star to run into trouble at the Sierra Blanca border checkpoint: Willie Nelson, Snoop Dogg and actor Armie Hammer have also been arrested there for drugs in the past.

The Idler Wheel, Apple's first album in seven years, was released this summer to rave reviews. She promoted the disc with a series of in-depth interviews, including a lengthy New York Magazine profile earlier this summer, Apple didn't shy away from discussing drug use, drinking "marijuana-laced lemonade" and smoking pot with writer Dan Lee.
