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!"
She later appeared dressed in a gray mini shift dress and talked about her podcast, Anna Faris Is Unqualified, which offers "not-so-great relationship advice from completely unqualified Hollywood types."
The actress, who has a son with husband Chris Pratt, then dispensed some words of wisdom about sex and dating to The Ellen DeGeneres Show audience members.
