Johnny Depp and Amber Heard aren't letting an engagement get in the way of having a little fun! According to a new report, Depp and Heard are not boring when it comes to spicing up their love life.

No Change In Career For Amber Heard?

"Johnny and Amber have the steamiest sex in Hollywood," a source told Radar Online about the beautiful couple. According to this longtime friend, Depp, 50, and Heard, 28, "have added erotic literature that's even more explicit than 50 Shades of Grey to their repertoire."

Whoa! We wouldn't expect anything else from the pair who met on the set of The Rum Diary and got engaged last Christmas.

"Amber introduced Johnny to some racy vintage paperbacks and now he's into collecting old photographic sex books and footage from the 1950s and earlier," the friend continued. "They'll read passages to each other from the books to spice up their already-hot relationship."

Was Amber Heard Pregnant?

Heard recently commented on why people are continually interested in her personal life. "For better or worse, I've always had a love life that seemed particularly salacious to some people," Heard told W Magazine. "Before, it was also seen as unconventional." Heard dated photographer Taysa van Ree previously, while Depp was with longtime partner Vanessa Paradis.

Whatever the couple is doing must be working! Depp was just spotted giving Heard a big smooch on the lips during a set visit to her latest film The Adderall Diaries. I'd always rather be passionate than bland," Heard said. "I can't imagine living a quiet life."
