AceShowbiz - Actress Ashley Greene fears she may have been breaking the law when she stripped off for a nude beach day on her honeymoon.

The Twilight star and her new husband Paul Khoury found a "partially nude" beach in Hawaii and he persuaded his bride to bare all.

"You kind of hike up behind this rock," she tells TMZ. "I don't know that it's actually legal, but we were there early."

And Ashley reveals she made sure her man knew he would be in big trouble if there were any problems: "(I said), 'If I get arrested and I miss my flight for this, I'm gonna kill you.'"

The Twilight star and her husband jetted off to Hawaii after tying the knot in a star-studded ceremony in San Jose, California on 6 July.

Ashley seemed relaxed once she agreed to get naked on the beach, even sharing a black-and-white shot of herself sitting by the ocean, taken from behind, on social media.

"He keeps me wild and free," she captioned the shot, adding the hashtags "#nudebeach" and "#honeymoon".

Ashley also posted a sweet snap of the newlyweds kissing in front of a waterfall, which she captioned, "#bliss".

Paul also shared a photo of the actress on Instagram as he gushed about his new wife, who he first began dating in 2013 and proposed to in 2016.

"I can't describe the way this woman makes me feel," he commented. "#MrsKhoury #honeymoon".

The couple wrapped up its romantic vacation at Nationals Park in Washington, D.C. for the MLB Celebrity Softball Game, in which Ashley played alongside the likes of Jamie Foxx and Taylor Kinney.
