Kathryn Hahn was completely embarrassed after her son caught her doing 'witch moves' for 'WandaVision' role: 'It was as if he just saw me getting out of the shower'

• Hahn said her kids were not impressed that she starred in "WandaVision," especially her teenage son.
• The actress said her son didn't enjoy seeing her doing "witch moves" at home.
• "Like it was as if he just saw me getting out of the shower," she said.

Kathryn Hahn's kids are not impressed that she played the entertainingly evil witch Agatha Harkness in the acclaimed Disney+ series "WandaVision."

"My kids would be making constant fun of me," Hahn revealed on EW and People's Emmy preshow livestream on Sunday about how it was like rehearsing Agatha around her house.

"Like my kid walked in one time while I was practicing my witch moves and he was like, 'Oh my God, Mom!'" Hahn said as she pretended to be her son and gave a look as if repulsed by what he saw.

"It was as if he just saw me getting out of the shower," she added. "He was so embarrassed."

Hahn has two children with husband, actor Ethan Sandler.

But Hahn knows deep down they're impressed by her work on the Marvel series.

"It's a little cool. He just can't let me see it," she said of her son. "He's a teenager!"

Hahn was nominated for an Emmy on Sunday in the outstanding supporting actress in a limited series or movie category. She lost to Julianne Nicholson for the latter's role in "Mare of Easttown."

Despite Hahn's loss, "WandaVision" did win several technical Emmys, including outstanding original music and lyrics for "Agatha All Along."
