Johnny Depp's girlfriend Amber Heard is the latest victim of nude celebrity photo hacking.

On Sunday, more than 50 topless pictures of Heard were posted onto 4chan and Reddit.

In one of the photos, Heard is holding up a sign apparently referring to her fiancé Depp as "Tonto."

Prior to Heard, the same celebrity photo hacking involved several Hollywood actresses, including "Glee" actresses Lea Michele, Becca Tobin and Melissa Benoist, "Hunger Games" star Jennifer Lawrence, "The Big Bang Theory" star Kaley Cuoco-Sweeting, and "Break Free" hit maker Ariana Grande.

The FBI told TMZ their investigation, which started since the first wave of celebrity photos were released, is still ongoing.

Comments about the leaked photos are yet to be released from Heard, who was recently announced as the third actress to join the cast of the stripper movie "Magic Mike XXL" after Andie MacDowell and Jada Pinkett Smith, The Wrap reported.

Heard, MacDowell and Smith will join Sofia Vergara's boyfriend Joe Manganiello, Matt Bomer, Cody Horn, Alex Pettyfer, Gabriel Iglesias, George Dawe, Mike Cassaway, Brandon Richardson and Channing Tatum who plays the title role.

Before "Magic Mike XXL," Heard will be seen in "London Fields" opposite Billy Bob Thornton, "The Adderall Diaries" opposite James France and "When I Live My Life Over Again" with Christopher Walken.

On the other hand, her fiancé stars in upcoming movies "Black Mass," "Yoga Hosers," "Mortdecai" and "Alice In Wonderland: Through The Looking Glass."

Recently, Depp was spotted in London with rocker Ryan Adams.

The 51-year-old famously known for his "Pirates Of The Caribbean" role played guitar on two songs "Kim" and a cover of "Mother" at Shepherd's Bush Empire on Sept. 18, Thursday, Metro reported.

This is not the first time Adams and Depp performed together. Earlier this year, Depp played guitar on the B-side of Adams' "Aching For More."
