Julia Louis-Dreyfus

Chances are, the text of Julia Louis-Dreyfus' back tattoo was the last thing people were focusing on when they were eyeing her recent nude Rolling Stone cover photo. But a few keen-eyed folks have picked up on an error in the shot.

The large back tattoo — the only thing Louis-Dreyfus dons in the racy photo — features the preamble of the U.S. Constitution, as well as John Hancock's signature prominently displayed on the Veep star's lower back. The only problem? Hancock signed the Declaration of Independence, not the Constitution.

Louis-Dreyfus, 53, addressed the mistake on Twitter, and jokingly blamed it on Mike McLintock (Matt Walsh), Selina's communications director on Veep.

"Hancock signed Dec. of Independence NOT Constitution. Yet another Mike f---up. Dummy. #veep #crackexcuse @VeepHBO @mrmattwalsh cc@rollingstone," Louis-Dreyfus tweeted Wednesday.
