And this is Katharine McPhee, American Idol runner-up (she was robbed), and actor of Smash, Scorpion, and Waitress fame.
For the sake of remaining as clear as possible, these are TWO separate women. Sophia on the left, Katharine on the right.

In case you were wondering, Sophia loved it too, commenting, "I legitimately cannot stop laughing."
