Underwood echoed the sentiment.


Do me a quick favor: close your eyes and picture Reese Witherspoon. Got it? Now close them again and picture Carrie Underwood standing next to her. Do you see what I see?

Between the blonde hair and similar smiles, the two superstars do kind of look like they could be sisters. It's a fact that both of them seem to have just realized and now they're really pumped about it. On Sunday night, Witherspoon posted a tweet about a woman who mistook her for Underwood. "To the woman in the parking lot who just asked me if I was Carrie Underwood: You officially made my day!" she wrote. 

Underwood immediately replied sharing the same sentiment. "YOUR day?!?!?!?! That lady just made my whole life!"

Witherspoon is no stranger to having doppelgangers. For years, people have said that her daughter Ava Phillippe is her twin. Now that we have added Underwood to her lookalike list, it's almost impossible to unsee it.
