Drew Barrymore was mistaken for being pregnant and had the best response: 'I'm just fat right now'

• Drew Barrymore undergoes a dramatic transformation while filming her Netflix show "The Santa Clarita Diet."
• The actress likes to "pig out" during filming breaks, explaining that she is a "foodie" who loves fettuccine alfredo.
• A stranger mistook Barrymore for being pregnant recently, and she clapped back in the most relatable way.

No one likes unwanted comments about their body, but Drew Barrymore just set the bar for the best kind of response. 

The star of Netflix's "Santa Clarita Diet" went on "The Late Late Show With James Corden" on Wednesday night, and shared a hilarious anecdote about a stranger who thought she was pregnant, and her incomparable clap-back.

When Barrymore was out with some fellow mothers and their children recently, she said one woman stopped the actress for what sounds like a seriously rude conversation.

"She's like, 'God, you have so many kids,' and I go, 'Well not all of them are mine, I just have two,'" she recalled. "And she said, 'Well, and you're expecting, obviously.' And I literally looked at her and go, 'No, I'm just fat right now.' And I walked out of the restaurant and I was like, 'Oh man, that is rough.'" 

Despite the discourteous encounter (good rule of thumb: never tell anyone they look pregnant unless you know for sure that they are), Barrymore seems to be laughing it off, joking that she channels Denzel Washington when she's not filming. 

"I heard Denzel Washington does this and I don't know because I just want to believe it, I don't want to know it's not true," she laughed. "But he just enjoys his life and then pulls himself back together when he's doing movies and looks amazing. So I'm giving it the full Denzel, even if that exists or not, and I let myself go."

When she is filming, Barrymore said she goes full vegan, exercising "almost every day." But when she isn't?

"Let's face it," she said. "I would much rather eat fettuccine alfredo all day long." 

Judging by the cheers from the crowd, she certainly isn't the only one.
