The win put Cardi B in the history books as the first solo female act to take the trophy.

On Tuesday, Lady Gaga tweeted, "It is so hard to be a woman in this industry.

"What it takes, how hard we work through the disrespectful challenges, just to make art," the singer wrote along with a photo of her and Cardi B laughing together at the Grammys. "I love you Cardi."

The "A Star Is Born" actress also called on others to support Cardi B.

"You deserve your awards," Lady Gaga tweeted. "Let's celebrate her fight. Lift her up & honor her. She is brave."
