The couple announced the heartbreaking news on social media, revealing their six-year-old pooch died after complications from knee surgery.
Coco, 37, penned a touching tribute to her dog admitting her "heart is hurting tremendously."
"He was my 1st baby with Ice. There'll never be another dog like him. Everybody that knew him thought he was very human like and so lovable," she began.
"His full name was Spartacus The Supermodel.. He was only 6.. I have been crying my brains out I'm shocked! #oneofakind (I will still keep their pages live @spartandmax because Max won't stop posting pics)."
Meanwhile rapper Ice T, 58, shared an adorable photo of Spartacus while admitting the pup was his "best friend."
"Terrible News: This morning I lost my Best Friend.. Spartacus died from a complication after surgery.. He had cancer in his knee.. So sad," the Law & Order: Special Victims Unit star said.
Spartacus often featured alongside the couple's other bulldog Maximus and their one-year-old daughter, Chanel Nicole, in sweet Instagram photos.
