As parents, “Teen Mom 2” stars Chelsea DeBoer and Jenelle Evans couldn’t help but sympathize with the families of the kids who were injured or killed in the recent Chattanooga bus crash. The reality stars took to social media to extend their prayers to the young students who were involved in the accident, as well as to their family and friends.

Between the two MTV stars, DeBoer was the first to express her disbelief upon reading about the Chattanooga crash. In a tweet she posted on Tuesday, the soon-to-be mom of two wrote that the news story gave her “chills” and that she is sending her prayers to the families affected by the accident.

Just a few hours later, Evans found out about the incident and took to Twitter, asking for prayers  for the southeastern city in Tennessee. The expectant mom also called out the driver of the bus for being “careless,” knowing that the vehicle transports children.

In a follow-up tweet, Evans got a bit emotional. The reality TV actress admitted how incident crushed her heart, adding that she’s sorry for the parents of the kids who were killed in the bus crash.

On Monday, Chattanooga citizens received disturbing news that a school bus from Woodmore Elementary School had crashed after its 24-year-old driver, identified as Johnthony K. Walker, recklessly sped and swerved during his drive in the afternoon, the New York Times reports.

Authorities said that five students were killed — four girls and a boy — and 12 others were rushed to the hospital. Half of the 12 were in intensive care. Another 19 were reportedly treated at the hospital but were released afterwards.

The National Safety Transportation Board are already reviewing what happened. The agency’s chairman, Christopher Hart, told NBC News that among the materials they will be reviewing are footage from the video cameras of the bus and a data recorded.
