Ashley Greene threw caution to the wind on her honeymoon with Paul Khoury -- and left her clothes at home. 

The Twilight star took to Instagram on Friday to share a sexy snap from her and Khoury's vacation in Hawaii, where they appeared to visit a nude beach. Greene looked away from the camera as she posed in her birthday suit, with waves -- and a couple other (clothed) beachgoers -- in the background. 

"He keeps me wild and free. #nudebeach #whiteboycray #honeymoon," she wrote alongside the pic. 

Pubic nudity is illegal on beaches in state parks in Hawaii, though there are several places where people still get naked. "Clothing optional. We chose none obviously," Greene wrote in the comments, adding that her husband "obvi" chose to strip down as well. 

The 31-year-old actress documented her and Khoury's racy trip on her Instagram Story, revealing that they chose to celebrate the last day of their honeymoon on the nude beach. "That's very romantic," she said, laughing. 

The newlyweds didn't spend their whole honeymoon in states of undress, however, as Greene shared a sweet pic of them sharing a kiss in front of a waterfall on Saturday. "#bliss," she captioned the photo, while Khoury shared another shot of his wife enjoying Hawaii's nature. 

"I can’t describe the way this woman makes me feel. #MrsKhoury #honeymoon," he wrote alongside the snap. 

Greene and Khoury, an Australian TV personality, tied the knot in a star-studded ceremony outside of San Jose, California, last week. Approximately 120 guests were in attendance, including Greene's Twilight co-star, Robert Pattinson, as well as Zac Efron, Liam Hemsworth, Brittany Snow, Cara Santana, Evan Ross and Lauren and Aaron Paul.

The actress told ET about her wedding plans in March 2017, revealing that they definitely wanted to incorporate the outdoors.  "I think we want to have a really intimate wedding, and then kind of throw a big party after," Greene mused. "We want it to be outside -- we want it to be surrounded by a lot of nature. He's a really big nature buff."

Lucy Liu, Suki Waterhouse and Snoop Dogg have joined James Franco’s post-apocalyptic thriller “Future World.”

Franco is co-directing with Bruce Cheung and co-starring with Milla Jovovich. Method Man, Margarita Levieva and Jeffrey Wahlberg has also joined the cast.

Bruce Cheung and Jay Davis wrote the “Future World” screenplay, from an original story by Franco and set in the barren landscape of a dystopian world, where a young prince from the Oasis (one of the last known safe havens) and a robot named Ash go on a daring journey of self-discovery through the violent and desolate world of the Wastelands.

Ambi Group, which is owned Andrea Iervolino and Monika Bacardi, is financing the film in association with the Fyzz Facility and Black Sparrow, and producing with Dark Rabbit Productions. Producers are Iervolino, Bacardi, Vince Jolivette and Jay Davis.

Ambi Distribution is handling global sales.

Ambi and Franco teamed to produce “In Dubious Battle,” which Franco also directed and starred in alongside Selena Gomez, Vincent D’Onofrio, Robert Duvall, Ed Harris, Bryan Cranston, Nat Wolff, Josh Hutcherson, Zach Braff, Analeigh Tipton, Ashley Greene, John Savage and Sam Shepard.

“‘Future World’ is a mesmerizing story with the kind of boundary-pushing creativity unique to James,” Iervolino said. “When you have the combined talents and gravitas of Milla, Lucy, Method Man, Suki, Snoop, and James interwoven through a wild story – what unfolds on screen is unreal.”
