The vile comment was made on Twitter, after Chrissy, 35, tweeted about watching the film Baby Mama starring Tina Fey and Amy Poehler.
"Watching Baby Mama again and Tina and Amy are just such an incredible pairing, always. They're not on here but someone tell them that if they're lookin' for a ménage I got a tricycle," said Chrissy.
Shockingly, one user responded to the tweet by writing: "So glad you've stopped using your terrible miscarriage as a means to keep promoting yourself."
Chrissy responded to the tweet with a simple: "Anything to please you, Katie" and was backed up by supportive followers.
One woman wrote: "20 years later, I'm open talking about my stillborn son. It's not self-promotion to work on healing and talk about all of your children."
While another added: "It's your story. Tell it how you want and need to tell it. Tell it when you want. Tell it as many times as you want. Apparently some people don't understand how to scroll. Peace and love to all who share their pain and trauma. You are helping yourselves and others."
"I'm so sick of seeing comments like this. Wtf is wrong with people? I can't even imagine how much courage it took for you to open up about your experience. One that SO many women can relate to. I'm sorry for everything you've been through. You don't deserve to be treated this way," added a third.
Chrissy and husband, John Legend, sadly lost their son Jack after complications during pregnancy. Ever since, she has been praised by fans for candidly sharing her heartbreaking miscarriage journey.
Chrissy - who is also mum to Luna, four and Miles, two - recently spoke out about her pregnancy loss in an interview, telling Ellen DeGeneres it was a "transformative experience" that "really saved" her.
"It was a really transformative thing for me and in a way it really saved me, because I don't think that I would've discovered therapy and then sobriety and this path of feeling good about myself and feeling like a new person," she said.
At the time, Chrissy posted a series of images from the hospital, after she and John first lost Jack.
Speaking about the pictures, she added: "Looking at those pictures now, it seems like so long ago. And also, of course, everything was such a blur. Even thinking back to it now, I am still in therapy about it and I'm still coming to terms with it."
