She may be one of the world's most glamorous women, but that doesn't stop Elle Macpherson suffering from the same beauty fails as everybody else.
The supermodel was spotted sporting a distinctly white under-carriage as she surfed with her children yesterday.
Wearing a high-cut wet-suit, Elle had clearly spent too long cooking in the sun the day before as the white patches from her bikini line were visible when she took to the waves in her home country of Australia.
And her tanning mishap wasn't the only thing going on in the gusset area either, as there appeared to be some rather unforgiving gathering, but the model remained unaware as she laughed and joked with her family.
Elle is currently enjoying a festive break in the sun with her children Arpad and Aurelius, as well as her father Peter and sister Mimi, and looked like a pro surfer as she demonstrated her impressive skills on the waves in Byron Bay.
Yesterday Elle chose to cover up as she took the boys kayaking, before flaunting her impressive figure in a classic white bikini.
That'll be where those tan lines came from then.
