Anna Faris is getting naughty this holiday season!
The 39-year-old Mom actress "accidentally" lost her skirt while appearing on The Ellen DeGeneres Show on Wednesday and danced around onstage in her underwear...her granny underwear.
Faris, who paired the look with a black long sleeve top and matching platform heels, appeared unfazed as she hugged Ellen DeGeneres.
"It's cold in here!" the actress joked.
She later tweeted about her appearance, saying, "Looking insane! Per usual! I had a great time on @TheEllenShow-thank you Ellen so much!"
