In a clip posted on the official Instagram page for the show, Kim, 43, attended the gender reveal party for her sister Kourtney Kardashian, 44, ahead of the birth of her baby with Travis Barker, 47.

While Kourtney and Travis sat up front at a drum set, Kim sat with the rest of the crowd waiting for the big reveal.

The reality TV star had her hair down and ditched her usual glam look for a makeup-free day.

As the baby’s gender was announced, Kim let out a huge scream.

The scream scrunched up Kim’s features, revealing dramatic lines above her eyebrows.

On Reddit, one fan zoomed in on the area and pointed out the curled shape of the lines, which came at regular intervals along her forehead.

Joking about the shape of the wrinkles, they asked: “What kind of mascara is this?”

Another responded: “Well, at least we know where the east cost’s [sic] entire botox supply is going to in the upcoming days.”

A third wrote: “She looks like her face is going to BURST!”

“Terrifying,” added a fourth social media user.

HEAVY HAND

While fans joked about Kim’s Botox use, the star previously admitted that she uses the injections beyond her face.

During one of the later episodes of The Kardashians Season 3, which aired last month, Kim made a shocking revelation about going under the knife amid much plastic surgery speculation.

The episode showed her at Kris Jenner’s home with her sisters Kourtney, and Khloe, 39, for a singing lesson.

The vocal coach provided a few tips, saying at one point: “I’m just talking on pitch. I’m not using my neck muscles. We have 425 muscles in the neck.”

The Skims mogul interjected, quipping: “Half of mine are probably Botoxed.”

Prior to the comment, the mother of four hadn’t confessed to getting any plastic surgery.

GREEN WITH ENVY

Alongside commenting on Kim’s appearance at Kourtney’s gender reveal, fans also theorized that she wasn’t happy with her sister’s news.

Sharing the video of Kim screaming, the original poster wrote: “Kim’s face is sending me.”

A second added: “She let her internal jealously screams come out lmao.”

“Her face is what looks like if you can’t hide the jealousy,” agreed a third, along with laughing emojis.

While fans thought that Kim was “jealous” at the gender reveal, she was also called out for her actions at Kourtney’s Disney-themed baby shower on September 24

Kim’s post from the day, captioned, “Baby Barker is coming,” showed off some moments from the luxury event – but most of the moments chosen featured Kim herself pouting and showing off her outfit.

In the comment section, fans of the Kardashians called out Kim for monopolizing the post, rather than showing off more of her family or the day itself.

One person blasted: “A post about baby barker and all of the pics but one are of you.”
