The photo was taken for, and appears on, the cover of Rolling Stone magazine.
It shows Dreyfus turning away from the camera and her back is covered by what looks like a tattoo of the preamble to the US Constitution.
The “uh oh,” comes when you read one of the signatures in the artwork.
There, written in BIG letters just above her rear end is the name John Hancock.
As the AP points out, the problem with that is, Hancock signed the Declaration of Independence, not the Constitution.
Dreyfus, who stars on the HBO series “Veep,” was playful about the error, tweeting that she was “in a Rob Ford-style drunken stupor" when the photo was taken.
Rolling Stone was a bit more serious about it with their explanation.
They say the Declaration of Independence was indeed inked on her body as well but it was not in view of the camera.
Then, the signature wouldn’t fit and was placed on the other side.
Paul Whitefield from the Los Angeles Times joked “hopefully, for Louis-Dreyfus’ sake, the tattoo isn’t permanent."
