The Kardashian/Jenners love throwing shade at their sister's exes. We saw this a couple weeks when Kim tweeted Lamar, Khloe's ex, and called him out about all the brothels he has been to.

Not even two full weeks later, and we see yet another comment. This time it is Kendall Jenner calling out Scott Disick about his very young girlfriend.

A fan account, Scottthelord, posted a picture of Disick and his girlfriend, Sofia Richie on Instagram.

The picture showed Disick and Richie in a car with his kids in the back. The caption read, "Its good to see them together," what Kendall commented next shocked everyone.

Kendall commented, "awww scott and his kids." Kendall's sarcastic comment made fun of the fact that Richie is only 19, which is 15 years younger than Scott.

Fans are having mixed feelings about Kendall's comment. While some find it absolutely hilarious, others are calling her out because Kourtney Kardashian's new boyfriend is 14 years younger than her, which is only a year less than Scott and his girlfriend.

"Sofia was really hurt by Kendall's bitchy comment "“ they used to be close friends, which makes it all the more upsetting," the source told HollywoodLife.com.

The photos seem to be the first time Scott has had his kids out with his new model girlfriend, telling us that things are getting serious between the two. The couple has now been dating for about four months from when the news was first heard about in September 2017.

Kourtney Kardashian has not publicly commented on the romance between Scott and Sofia.

Do you think Kendall's comment was offside, or hilarious?
