That’s not hot.

Paris Hilton fans are expressing concern over her kids’ car seat setup after a TikTok video showed off her “new #SlivingMom van” Monday.

Phoenix, 1, and London, 6 months, were adorably dressed up for a Mother’s Day brunch in the footage.

Hilton’s followers, however, were focused less on the little ones’ outfits and more on their car seats facing forward, as well as the use of both a latch and a belt.

“Please hire someone to install car seats,” one social media user commented, while another offered to “come help [her] with the straps” to keep the “babies as safe as can be.”

A third wrote, “Please dble chk [sic] the car seat manu’s recs on if you can use the latch & belt at the same time. Usually hard no. Also, rear facing until 2ys is usually law.”

Others insisted son Phoenix and daughter London were “fine.”parishilton/TikTok

Others, however, defended Hilton’s setup and pointed out that Phoenix and London were “not strapped into a typical car” and were “fine.”

Another called the reality star’s execution “perfect” — while some speculated that the new mom was simply playing a joke on her followers.

Hilton’s rep did not immediately respond to Page Six’s request for comment.

The “Stars Are Blind” singer, 43, welcomed her baby boy via surrogate in January 2023 after keeping the pregnancy a secret from the public — and her immediate family.

“I didn’t want my son coming into this world with any negative energy,” she explained to Romper in December. “I’m really happy I did it that way … without the outside world chirping in.”

Hilton did the same when daughter London arrived that November.

The DJ waited four months to show her baby girl’s face via Instagram, finally revealing London’s features in April family photos.

Hilton previously clapped back at the parenting police in December 2023 when her diaper-changing confession on “Paris in Love” went viral.

“I joked about changing a diaper for the first time, which, let’s be honest, was just me having a bit of fun,” she tweeted. “In all seriousness, when it comes to being a mom, I’m fully involved and loving every moment of it.”
