The Chromatica singer wore her most daring outfit to date on the VMAs red carpet in 2010.
"You would never tell Travis Scott or Adam Levine that he couldn’t turn the beauty light off," the singer said.
"Hair and makeup by exhaustion," the singer joked on her Instagram story.
Returning to the stage that generated so much controversy for her in 2013, she performed her new single Midnight Sky.
Gaga performed a string of tracks from her chart-topping album Chromatica in a personalised face covering.
And it seems the actor has taken the incident in good humour.
The Grease star appeared to confuse RuPaul's Drag Race star Jade Jolie for Taylor Swift during Monday's ceremony.
Their first meeting backstage at the VMAs was, obviously, a noisy one.
Taylor Swift used her Video Of The Year acceptance speech to raise awareness of LGBTQ rights in the US.
