"And if you think that's weird, Donald Trump has been impersonating the president for almost a year," Corden jokes.
The wild claim was sparked when people watching Donald Trump's White House briefing noticed some oddities: the first lady was wearing large sunglasses that covered the majority of her face and the president even felt the need to reassure the press that it was indeed his wife standing next to him.
"And if you think that's weird, Donald Trump has been impersonating the president for almost a year," Corden said in his monologue Monday night. "But the rumors that Melania was a body double started swirling when people noticed that this Melania and Donald actually seem to like each other."
Corden then played a clip in which he acted as Melania's body double, nodding her head at everything Trump was saying and eventually reading Hillary Clinton's new tell all-book "What Happened?"
Fallon, on the other hand, announced that the NBC late-night show was able to score an exclusive interview with the mysterious woman. In order to prove her true identity, the comedian put her to the test with a series of simple questions only the real first lady would be able to answer.
What is the name of the city you were born? "Did you say Slovakia?"
Where in the White House is the first lady's office? "It's in the attic."
As first lady, what have you said are your three main goals? "Bullying, stop it. Sugar, keep eating it. Make sure you remember friendship is real."
