And now that Francis is apparently engaged, he wouldn’t want his future wife to know what he was really up to.

from www.tmz.com – “Girls Gone Wild” founder Joe Francis is on the war path over a “tell-all” book [titled Flash! Bars, Boobs and Busted: 5 Years on the Road With Girls Gone Wild] written by one of his former camera guys … a book that allegedly details incidents involving drugs, sex and jail.

The dude who wrote the book is Ryan Simkin — who began shooting naked, drunk chicks for Joe back in 2002.

In his lawsuit, Francis claims Simkin — like all of his employees — was required to sign a non-disclosure agreement, which strictly prohibited him from “writing and publishing any tell-all books about their work.”

So, according to the docs, when Francis heard that Simkin had a book on the way — he wrote up a little something of his own … a breach of contract lawsuit.

Francis is also suing the publisher — it’s unclear how much cash Joe is hoping to collect.
