50 Shades of Princess Mette-Marit!

Norway’s book-loving princess is set to open a major exhibition devoted to Norwegian erotica – including the works of an author prosecuted for obscenity.

Princess Mette-Marit, 42, will launch “The Red Ruby – Erotic Transgression In Norwegian Literature” at Oslo’s National Library on September 24, the Norwegian Court confirms.

“We greatly appreciate Princess Mette-Marit opening this exhibition,” says the National Library director Aslak Sira Myhre, who concedes some of its subject matter, which chronicles Norwegian erotica from 1880 until now, is “controversial.”

The show takes its title from The Red Ruby, a novel by Agnar Mykle that was successfully prosecuted for obscenity in 1957 and subsequently banned.

The book tells the story of an economics student just before World War II who thumbs his nose at convention and features vivid “descriptions of extreme sexual acts.”

Both Mykle, who based the story on his own experiences, and his publisher were prosecuted. They only escaped imprisonment after the entire book was read out loud in an Oslo courtroom.

But the year-long struggle to establish his innocence led to the author’s divorce and a breakdown before he died in 1994.

The princess, a mom of three who describes herself as a “dedicated bookworm,” often shares her passion for reading – including the most popular erotic fiction of the modern era.

Asked earlier this year if she’d read 50 Shades of Grey, she told Norwegian newspaper Dagbladet, “I have read some of it, haha!” before firmly changing the subject.
