Gwyneth Paltrow went on Ellen DeGeneres' show yesterday (April 25), and during their chat, the topic of conversation turned to that sheer dress Gwynnie wore to the 'Iron Man 3' premiere.

Paltrow explained to the audience that she changed after a prior engagement and that's when she realized the dress would force her to go commando. "Let's just say everyone went scrambling for a razor," she said, "so I went from being the most beautiful to the most humiliated in one day."

If you don't know what the razor was for, we're not going to explain it to you.

The comment threw off Ellen so much that after much flustered blushing and giggling (from both ladies, actually), the generally composed host was forced to go to a commercial break.
