Melania Trump made a rare public appearance at a military parade in Washington, coinciding with Donald Trump’s 79th birthday. Her return to the spotlight instantly reignited the long-running conspiracy theory that she’s been replaced by a body double.

The bizarre theory, which started in 2017, claims Melania is sometimes replaced by a lookalike. It gained traction again after a report alleged she spent fewer than 14 days at the White House during her husband’s first 100 days in office.

Melania was seen smiling and engaged early in the parade, but later appeared tired or disinterested. Her lack of signature sunglasses or hats didn’t stop online sleuths from speculating. “She seems older and wider… is that a body double?!” one user asked. Another, a Trump supporter, confidently wrote: “This is a body double and not a very good one.”

While Melania remains silent, Donald Trump previously slammed the theory as “fake news,” accusing the media of photoshopping images and fueling “deranged” rumors.
