Martha Stewart is getting real.

The lifestyle guru admitted in the trailer for her new Netflix documentary “Martha” that she had an affair during her decades-long marriage to her only husband, Andrew Stewart.

“Young lady, listen to my advice, if you're married and your husband starts cheating on you, he's a piece of —,” the 83-year-old said in the trailer. “Get out of this marriage.”

“Didn't you have an early relationship?” A producer can be heard as a home and garden maven.

“Yeah, but I don't think Andy knew about it,” Stewart replied.

He added in the trailer that he was “thought crazy” as his career converged, “but it worked.”

In a 2020 interview with People magazine, Stewart admitted that the divorce was difficult for her.
