Melania Trump flashed a rare big smile while getting off a helicopter with Donald Trump as they traveled to the final presidential debate, and critics used theories about why it was a ‘fake Melania’.

A newly surfaced photo that shows Donald Trump, 74, and a very happy looking Melania Trump, 50, getting off of the Marine One helicopter to board Air Force One last week is bringing back theories that a body double for the First Lady is sometimes being used. In the pic, which was taken as the husband and wife were making their way to Nashville, TN for the final presidential debate, Donald is wearing a suit and waving to onlookers as Melania stands behind him in a sleeveless black dress and sunglasses and also waves while flashing a big rare smile. Since the beauty has often made headlines for looking miserable whenever she’s around the president, it didn’t take long for Twitter users to suspect the recent smiling snapshot was of a “fake Melania”.

“I like a president who doesn’t have to hire a First Lady stand-in,” one Twitter user wrote along with “#FakeMelania.” Actress Meredith Salenger also wrote about her thoughts on the photo. “Holy sh*t this is an obvious one. Do we just let that sh*t slide?” she asked in response to a tweet from writer/director Zack Bornstein that read, “The only thing I’ll miss from this administration is them swapping in new Melanias and just pretending we won’t notice like a 4-year-old with a guppy.”

“Folks, there is a body double running around for Melania. Know how I know? She’s smiling,” another Twitter user cheekily tweeted, while another compared Melania’s teeth in the helicopter photo to in a previous photo. “Notice the two front teeth. Melania’s are more squared…THAT AIN’T HER in the other photo. #FakeMelania,” the tweet read.
