Jerry O’Connell stripped down to a bejeweled speedo on Tuesday’s “The Ellen DeGeneres Show.”

The 38-year-old very buff actor removed his pink robe to reveal his teeny tiny sparkly speedo before entering the dunk tank in support of Breast Cancer Awareness month.  O’Connell was a good sport as he made excuses about the coldness of the studio, saying it didn’t show him in a good light.

He then sat in the hot seat while his “Mockingbird Lane” costar Portia de Rossi, DeGeneres, and his wife Rebecca Romijn tried to soak him, Portia hit the bull’s eye.

Watch the video below and tell us what you think of the adorable O’Connell in the tank!!
