Johnny Depp and Amber Heard read erotic literature together to have the steamiest sex in Hollywood. At least that's what the buzz is.

According to a source, the Pirates of the Caribbean star and his girlfriend added erotic literature that was even more explicit than 50 Shades of Grey to their collection, Radar Online reported.

The source spilled the beans that the American actress introduced the 50-year-old actor to some racy vintage paperbacks and then he started collecting old photographic sex books and footage from the 1950s and earlier.

The spy further said that it was pretty weird, but the couple got a new thing every now and then and reading erotic literature was this month's fun thing they did together.
