Anderson Cooper has admitted to adopting a fake persona on Instagram to help his mother, Gloria Vanderbilt, sell her artworks.

The 54-year-old CNN anchor appeared on the "Late Night with Seth Meyers" Monday and confessed that he pretended to be a woman named Monica and claimed to be an assistant to his mother, who was a well-known painter.

"But around the time she was 91... she [Vanderbilt] wasn't painting," Cooper recalled as per the New York Post. "[Then] I introduced her to Instagram, which she thought was, like, magic. I got her on Instagram, then I created an account for her artwork to get her out of bed and paint."

Vanderbilt's Instagram account gained thousands of followers quickly and users started asking how they could buy the artworks. However, she didn't have any assistant to take care of her online business at that time, so she came up with the idea of inventing a lady named Monica.

"She was like, 'OK, why don't we invent a lady of a certain age named Monica, who's a long-time trusted assistant, and you be Monica and you answer all the DMs on Instagram to buy my artworks,'" Cooper explained.

He went on to talk about what he had to go through the next couple of years after agreeing to act as Monica.

"I'd be in Baghdad and in between things I'd be [talking to a buyer] like 'Would you like a laminated white frame?' as Monica," Cooper recalled.

The official Twitter handle of the late-night show shared the video Tuesday.

Fans in the comments section praised Cooper for being supportive to his mother.

Vanderbilt died at the age of 95 in 2019 due to stomach cancer.

Earlier this month, Cooper spoke with Andy Cohen on "SiriusXM's Radio Andy" and recalled the final moments he spent with his mother.

"We had an amazing last week or two together. We would just lay on her bed and hold hands," Cooper told Cohen.

The journalist revealed how he used to watch an old video of his mother singing "Is That All There Is" while holding her hands.

On the work front, Cooper will be seen in a documentary titled "Bodyslammed: Folk Hero vs. Billionaire" alongside TV hosts Stephen Colbert and Seth Meyers.
