Little Chanel turned one on Monday (28Nov16), just hours after the stars revealed their first pet Spartacus had passed away following complications from knee surgery.

"Terrible News: This morning I lost my Best Friend," Ice-T wrote on social media on Sunday night (27Nov16). "Spartacus died from complication (sic) after surgery... He had cancer in his knee...So sad."

Coco also shared her despair with fans online, and decided to postpone celebrating Chanel's big day in tribute to their six-year-old pooch.

"Cuz I've been mourning over Spartacus I put Chanel's Birthday on hold (which was today)," she wrote on Monday. "I feel I need 2 honor Sparty before a celebration (sic)."

Instead, Ice-T and Coco marked their daughter turning one on Tuesday with a series of sweet posts online.

"Yesterday was @babychanelnicole First Birthday," the Law & Order: Special Victims Unit actor shared. "She's the sweetest and happiest baby I've ever seen. LOVE is not a big enough word. Happy Birthday baby."

Meanwhile, her proud mum posted, "One year ago yesterday I got the best gift in the world @babychanelnicole. Happy Birthday baby girl! The love I have for her no words can explain."

The couple also has a second bulldog, named Maximus, and Coco has promised to keep the Instagram page dedicated to the two dogs running following Spartacus' death, "Because Max won't stop posting pics".
