Ashley Greene Says It Was New Husband's Idea to Hit Nude Beach on Honeymoon

Ashley Greene's new husband likes to keep it real and raw ... and she's more than willing to accommodate!

We got the "Twilight" star at LAX Wednesday and asked her about her recent honeymoon in Hawaii ... where Ashley and Paul Khoury hit up a nude beach. Turns out, Paul likes to hang loose and she was happy to tag along ... in her own way.

As Ashley tells it ... her Australian hubby's baring all at home all the time, so a few strangers checkin' out the goods is no big deal. But, the newly married couple had to be strategic about the whole thing ... turns out the nude beach might not even be legal!
