Host Gigi Hadid squinted her eyes, pursed her lips and put on a fake accent to mock Melania Trump as she said: "I love my husband, President Barack Obama and our children Sasha and Malia."

Some fans watching at home took offense to the model’s impression and took to Twitter to vent their frustration.

Gigi Hadid showed the highest form of disrespect possible to the next first lady. Unforgivable! #AMAs

@TommyHilfiger @GiGiHadid Her imitation of Melania Trump was like a mean girl in high school. Disgraceful.

It is not the first time they have used their TV time to chastise a president. In 2004, they pulled a similar stunt while performing their single “American Idiot,” which was aimed at then-President George W. Bush.

Billionaire Mark Cuban also took aim at his foe, Donald Trump, when he was asked by Idina Menzel what he would be looking forward to in 2017, he replied: “Not being invited to the inauguration.”
