The Austin Powers star was at the Victoria and Albert Museum in London with her shoe designer pal Patrick Cox recently when she spotted a 16th century bed.
It turned out to be the Great Bed of Ware, a giant, three metre wide four-poster bed.
Her faux pas was so great, security felt it appropriate to escort Hurley from the premises. But hey, at least she got the photo.
She later posted it to Instagram with this caption:
While most of Liz's followers thought the situation was funny, some criticised her for breaking the rules. kimlakin said "How totally disrespectful of the museum. Typical privileged elitist behavior. Rules don't apply to you do they?".
We're sure she'll think twice before taking her next selfie.
Have you ever gotten in trouble trying to take the perfect selfie?
