Los Angeles, California - Actor and TV host Nick Cannon took to social media to share a heartfelt tribute to his late son, Zen, who passed away last year.

Monday marked a year since baby Zen passed after being diagnosed with Hydrocephalus, a buildup of fluid that puts pressure on the brain.

Cannon (42), who was reportedly hospitalized over the weekend for pneumonia, explained in an Instagram post that while he was on the mend physically, "Mentally and Spiritually I'm broken."

"I can't believe it's been a year already since the toughest day of my life occurred," The Masked Singer host shared. "Such a painful anniversary. Losing a child has to be the heaviest, most dark and depressive experiences that I will never get over. A mixture of guilt, pain, and sorrow is what I suppress daily."

"I am far from perfect," he continued, "and often fall short and make decisions in my life that many question, but anyone who knows me knows my heart.

"I love hard, I love big and I love with my entire Heart and Soul and I just wish my Little Man could've felt more of that love while he was here on Earth," Cannon wrote.

"Continue to Peacefully Rest My Son, Zen Scott Cannon. We Love you Eternally," Cannon concluded.
