"The Late Show with Stephen Colbert." CBS/YouTube After almost five months living apart, President Donald Trump and his wife, Melania Trump, are now living together in the White House.

The first lady moved in on Sunday after staying back in New York City in Trump Tower so their 11-year-old son, Barron, could finish his year of school.

On Tuesday's episode of "The Late Show," Stephen Colbert checked in on how Melania was settling into her new home by bringing back the actress Laura Benanti for her great impression of Melania.

"It was so lonely in New York doing whatever I wanted whenever I wanted," Benanti as Melania said. "I called it my prison of freedom."

Colbert then asked if she was all moved in. She said she was and showed off some of the things she brought with her, like a toothbrush and a framed picture that showed her apparently swatting away her husband's hand during their trip to Tel Aviv in May.

Benanti said the image, which had instantly gone viral online, was of "the most cherished moment of marriage to my husband."

When Colbert asked her if that was, in fact, a picture of her slapping away her husband's hand, she corrected him: "His hands are so small I thought it was a mosquito."

And when Colbert brought up the rumors that her husband possibly could be impeached, she said she was ready for a long stay in the White House.

"Here's the thing: America took a vow, and Donald Trump is our president, for better or worse, for richer or even richer, in sickness and in no healthcare," she said. "And we must honor that, no matter how often America fantasizes about being with Justin Trudeau."
