"So because I'm a mother I can't wear a pretty dress that makes me feel beautiful?"

Heather Rae El Moussa had some words for a social media commenter who said she dressed in an inappropriate way for a mother.

The "Flipping El Moussas" star, 37, shared a screenshot in her Instagram story of a comment someone wrote on one of her recent Instagram posts.

"The dress is not appropriate. Your a mother now," the commenter wrote.

The dress in question was a floor-length red, lacy gown that El Moussa sported as she posed alongside husband Tarek El Moussa, 43, in a series of holiday photos.

"so because I'm a mother I can't wear a pretty dress that makes me feel beautiful?" the former "Selling Sunset" star replied to the commenter. "What does that have to do with anything?"

"I am still a human and my name is heather I'm not just a mother," she also wrote. "Choose joy."

El Moussa added some more thoughts about the comment in her Instagram story.

"Comments like this make me laugh," she wrote. "I don't even get offended anymore by the rudeness of others. I choose to spread joy not hate."

El Moussa's holiday slideshow included photos of her son, Tristan, whom she and her husband welcomed in January 2023.

They were also joined by Tarek El Moussa's son, Brayden, 9, whom he shares with ex-wife Christina Hall. He and Hall also share a daughter, Taylor, 14, who was not shown in the photos.

Heather Rae El Moussa also responded in the comments on her post to another person who wrote, "She looks just like Christine he has a type."

"her name is Christina," she wrote back. "Ya most do have a type..."

Some of the TV star's former "Selling Sunset" castmates praised her holiday look in the comments, including Maya Vander, who wrote, "hot hot."

"Wow-stunning!" Chrishell Stause chimed in.

Several commenters also appeared to refer directly to the original commenter's negative reaction to El Moussa's look, and challenged the idea that moms can only dress a certain way.

"People are ridiculous. You can be a mother and still look stunning in a gorgeous gown!!" one person commented. "Just because she is a mother doesn't mean she has to stay at home in pjs and never go out. Let the woman live! If I felt that comfortable in my postpartum body I would wear that dress too!"

"She is a Mom. She is a wife. She is a stepmother. She is human. And she is absolutely beautiful in that dress!!" another person wrote.

El Moussa opened up about her fertility journey in an essay for TODAY Parents in 2022, sharing that being with Tarek El Moussa changed her mind about wanting a child.

When they began their relationship, she and her now-husband were both "a hard no on babies," she said.

However, witnessing her husband as a dad to his son and daughter "completely changed" her mind about wanting a child, she wrote.

"Tarek and I communicate very well with each other, so I didn't hold back about how I was feeling," she wrote. "At first he was like, 'Oh, I'm not sure... I already have two beautiful children.' But the more we discussed it, the more excited we both became. Now, he'll just look at me and go, 'I can't wait to have a baby with you!'"

The El Moussas announced the arrival of their son, Tristan, in a February 2023 Instagram post.

"Our baby boy is here 🤍 1.31.23," the couple captioned the joint post. "Mama & baby are happy, healthy, tired but doing well. Our hearts are so happy."
