The mother-of-one, who is seen perching on a stool among a stack of cardboard boxes, captioned the photo: “Boxing Helena .. Worked with the amazing @aleburset on an exciting book project - here’s a few BTS shots #interningatfedex.”

The Danish beauty started her modeling career after she won the Miss Universe Denmark crown in 1986 when she was just 17 years old.

She went on to compete in the Look of the Year in 1987 and was a finalist.
