'Some of us can't do it!' she told the crowd at London's O2 arena on Tuesday.
Adele has a few choice words for mom-shamers!
Specifically, Adele called out those who pressure new mothers to breastfeed their children while performing at London's O2 arena on Tuesday night. During an informal question and answer session with her fans, the 27-year-old singer responded to an inquiry about "breastfeeding mummies" in typically incredible Adele fashion.
"You know what, the pressure on us is f**king ridiculous," she began. "No worse people who put pressure on. You can go f**k yourselves, alright? Because it's hard. Some of us can't do it!"

Adele went on to get personal about her own struggles breastfeeding her son, Angelo (it all starts around the 00:50 mark).
"All I wanted to do was breastfeed my kid and then I felt like, if I was in the jungle right now, back in the day, my kid would be dead because the milk's gone," she continued, drawing chuckles from the crowd. "It's not funny!"
The Grammy winner later went on a hilarious tangent calling Mariah Carey "biblical." Watch the whole thing unfold in the video below.
READ: Adele Says Motherhood Is 'F**king Hard'
While Adele has remained fiercely protective of her family, including her 3-year-old child with partner Simon Konecki, this isn't the first time she's spoken out on the surprising struggles of motherhood.
"It's f**king hard. I thought it would be easy," Adele told i-D magazine in October. "'Everyone f**king does it, how hard can it be?' Ohhhh..."
With what the writer described as a dramatic sigh, Adele continued: "I had no idea. It is hard but it's phenomenal. It's the greatest thing I ever did. He makes me be a d**khead, and he makes me feel young and there's nothing more grounding than a kid kicking off and refusing to do what you're asking of them. It used to be that my own world revolved around me, but now it has to revolve around him."
Around that same time, Adele told NPR that she was traveling with little Angelo as she did press promoting her new album, 25.
"My kid comes everywhere, and he is so grounding," she explained. "I was saying the other day that doing it again with a kid this time, it's making me more tired than normal, but on the other hand, he just brings me back down to earth. So I'm feeling pretty balanced about it, actually, and I have only him to thank for that."
