The talk show host revealed her very cheeky costume during Wednesday's Halloween-themed episode of The Ellen DeGeneres Show, dressing up as Modern Family star Sofia Vergara, whose slinky green Zuhair Murad gown infamously split along her rear during the Emmys.
"I am easy breezy beautiful CoverGirl from Colombia. Happy Halloween. As you can see, I put my pumpkins out," DeGeneres, who is also a CoverGirl, said, affecting Vergara's accent. "I get so much work with this fake accent," she added.
But the comedienne was interrupted by the real deal when Vergara made an appearance, bluntly telling DeGeneres, "Your ass looks huge."
"I have to say, it is looking in a mirror," DeGeneres told Vergara, who called the costume, "ridiculous."
In true Ellen style, DeGeneres replied, "I feel sexy," before the two bombshells started dancing.
