The 24-year-old took to her Instagram account to share a photo of herself alongside family members, including mom Kim Zolciak-Biermann, sister Ariana Biermann and stepdad Kroy Biermann, dressed in all black with a heartfelt message about the hit-and-run death of Ethan.

As E! News previously confirmed, Ethan, a longtime family friend of the Biermanns, passed away following a car accident on Saturday, April 3 in Atlanta, Ga. When news of his death first broke, Kim took to Instagram to further express her grief on Brielle's behalf.
"Nothing I wouldn't do for you @briellebiermann," Kim shared alongside a photo from what appeared to be Ethan's memorial service. "I wish I could take all of your pain away. I LOVE YOU! Ethan taught us all one important thing LIVE LIFE EVERYDAY TO THE FULLEST!"
