Duff posted a photo of her killer figure on Saturday, alongside an upcoming lunch of freshly caught fish. "Caught this today spear fishing!!!" she captioned the snapshot. "The only reason I don't feel terrible is because I'm eating it for lunch."
The 28-year-old actress also made friends with an iguana, going to great lengths to secure that perfect shot. "Found this little weirdo today!!" she wrote. "He was Huge... picture doesn't do it justice... I climbed up a tall room service cart to get this picture FYI."
