Ellen DeGeneres dresses up as Sofia Vergara for Halloween

(CNN) -- Sofia Vergara's Emmys dress this year was unforgettable - so much so, that Ellen DeGeneres decided to wear it as her Halloween costume.

But if you followed Sofia Vergara on Twitter, you know that DeGeneres' costume wasn't as straightforward as it looked.

Wearing padding to create an exaggerated imitation of Vergara's curves, DeGeneres joked while trying out her best impression of the "Modern Family" star and pointing to her chest, "as you can see, I put my pumpkins out."

And then, she went in for a spin ... showing a sizable split in the backside of the dress, just like the one Vergara experienced in real life at the Emmys. (Vergara tweeted at the time that it happened 20 minutes before "Modern Family" nabbed another award, but she was upbeat about it, posting, "I luv my life!!!!")

On DeGeneres' show Wednesday, as the comedian joked about how much work her "fake accent" pulled in, a more serious (at first) Vergara took the stage.

After doing a solid impression of what DeGeneres sounds like - and telling her she looked ridiculous - Vergara dissolved into laughter, and taught her a few Spanish phrases for the road.

But DeGeneres isn't the only star with a celebrity-inspired costume - Miley Cyrus, judging from her tweeted photo, is going as Nicki Minaj.
