Sports Illustrated models Erin Heatherton and Emily DiDonato

Supermodels Erin Heatherton and Emily DiDonato ascended to the top of One World Trade Wednesday morning to talk all things Sports Illustrated.

The annual swimsuit issue of the magazine hits newsstands next month but Erin says one particular wardrobe malfunction involving body paint won't be making it into the issue.

The finished product sure looks effortless. But the girls assure me there is lots of discipline, self-control and training leading up to a big shoot.
