As well as Tristan, Andrea - who worked as a school bus driver - is survived by sons Dishawn, Daniel and Amari, and her husband Trevor Thompson.
In 2020, this year, Tristan took to social media on Mother’s Day to pay tribute to Andrea as he thanked her for all the “sacrifices” she had made throughout his upbringing and felt “lucky” to be her son.
He wrote: “Happy Mother’s Day Mommy! One day isn’t enough to praise and lift you high. Everyday is your day. Thank you for all the sacrifices you made for me and my brothers. I love you and I’m soo lucky to have been chosen as your son[heart emoji] Not all superheroes wear capes.”
Since news of Andrea’s sudden death, Kris Jenner has posted a tribute telling fans she is “heartbroken” about the news.
