Marcia Gay Harden lets her makeup artist son use her face to practice

Let’s face it. It’s a makeup artist's dream to have a celebrity face in the chair to practice different looks on.

And Marcia Gay Harden’s son wisely uses his Oscar-winning mom’s face to perfect his craft. Harden told ABC News that her son is just starting out in the business, but he’s already glamming her up for red carpets.

“My son Hudson is amazing,” Harden said in an appearance on “Popcorn with Peter Travers.” “We were upstate in the barn and he said, ‘Mom, I’ve done myself and I need to do you or one of the sisters. Can I please do you? And I said, ‘Sure buddy.’ So we went upstairs in the barn and we set up some rudimentary lighting. And he did a whole makeup look on me. And it’s great.”

Fans had an opportunity to see Harden and her son in action when he posted the video of their makeup session on YouTube.

In her new Lifetime TV movie, "Love You to Death," Haden’s makeup is taken to a different extreme. In fact, she’s hardly recognizable. Haden plays the mother in a real-life story about a woman who has Munchausen syndrome. She wears a fat suit to channel the character.

“It’s weighted," Harden explained. "There’s sand and things in the legs. And it’s a lumpiness because the mom got really obese," Harden, 59, told Travers.

“She looked unhealthy. And I really wanted that to be a part of it. I felt like the bigger she got, in relationship to the more she was sucking from the daughter, the more life she was pulling from the daughter.”

“And so I really wanted to have the burden of carrying all of the weight of what she was doing to the daughter around with me," Harden continued. "So that the first part of understanding the character, was just understanding that.”
