Ouch! Kate Upton falls during topless photo shoot

Kate Upton proves that modeling can be a hazardous gig.

The 25-year-old bombshell took a tumble while striking a sexy pose during a Sports Illustrated photo shoot in Aruba this week.

Upton was standing on a rock, wearing nothing more than a tiered tulle skirt, before she painfully toppled into the water. The crew quickly came to her aid and helped her up.

But being the SI veteran that she is, Upton was photographed laughing off the incident while wrapped in a towel.

The fiancé of Houston Astros pitcher Justin Verlander also posed in a skimpy black swimsuit during the shoot.
