Nick Cannon and Alyssa Scott honored their late son’s first birthday with the founding of a pediatric cancer foundation.

Cannon took to Instagram on Thursday to announce the launch of “Zen’s Light,” a foundation named after his and Scott’s baby boy, who last December passed away at just five months old following a battle with brain cancer.

“June 23rd will forever be a day of celebration,” Cannon captioned a picture of himself and Scott at a lighting ceremony in their son’s honor. “A beautiful lighting ceremony to honor the life of an Angel. Zen’s birth has now transformed into ‘Zen’s Light.’ We are proud to announce his new foundation that will help so many others in this world.”

Cannon continued, “‘Zen’s Light’ mission is to foster global excellence in hope, grief-care, and pediatric healthcare for families and children in need. Thank you for everyone who joined us at this inaugural event...Can’t wait for next year where our Lighting Gala will continue grow to help find a cure for pediatric Cancer, further research and help console more families during difficult times.”

Scott also hopped on Instagram to share a tribute to Zen, admitting that she is trying her best “to remain optimistic,” but “can’t help but cry out.”

“Happy heavenly birthday Zen,” she captioned a picture of the pair together shortly after his birth. “At the root of all the emotions I have today there is insurmountable love. I always try my best to remain positive but right now I can’t help but cry out ‘it’s not suppose to be like this.’”

She continued, “In my mind I can see him smashing his cake and crawling around, tugging at my legs. But the reality is I will be the one to blow out his first candle. I will be wishing he was still here with us.”
