The Jonas Brothers were freaked out during a recent visit to Madame Tussaud's waxwork museum in New York - when they stumbled across the decapitated heads of assassinated leaders; and U.S. Secretary of State Hillary Clinton.

The siblings unveiled their own wax likenesses at the famous tourist spot and then were given an all access pass to explore the museum.

And Joe and Kevin Jonas fear they may have uncovered an area of the museum that is out of bounds to everyone but staff.

The back room was full of assorted legs, arms and heads from other public figures, who are no longer on display in the museum.

Joe says, "They closed off the haunted section and... all of a sudden I'm seeing, like, Abraham Lincoln. All the lights were off." Kevin adds, "There was a lady stuck to the wall with an axe through her. She looked real... I was like, 'Ah, I didn't do it!'"

Joe recalls, "There was, like, a closet of this stuff they use occasionally and Hillary Clinton's head was on the ground."

-Good news JoBro fans: Joe Jonas says they'll never break up!
