Awkward moment Melania Trump’s smile turns into a sad frown the second Donald Trump looks away during his inauguration

MELANIA Trump struggled to keep up appearances in a recently-posted video from husband Donald's inauguration.

The First Lady was filmed beaming at the newly-elected President as he took the applause of the crowd at his swearing-in ceremony.

But the moment Trump turns his back on Melania, 46, she breaks into a sombre-faced scowl.

The Slovenian-born former model was the star turn at Friday's inauguration.

Trump's third wife rallied her family, adjusting son Barron's tie before having an awkward high-five exchange with her ten-year-old boy.

She had earlier carried a gift-wrapped Tiffany present to the Obamas on the steps of the White House.

Melania was compared to 60s style icon Jackie Kennedy during the ceremony.

Her baby blue outfit bore a striking similarity to one worn by the glamorous wife of assassinated White House chief John F. Kennedy.
