US comedian and presenter Nick Cannon has revealed the two-year-old son he shares with Abby De La Rosa has been diagnosed with autism.

“Our beautiful boy experiences life in 4D and teaches us something new every day. His love, strength and brilliance light up every room he enters,” a shared Instagram post said.

“On this World Autism Awareness Day, we extend our embrace to families worldwide, acknowledging shared challenges and championing understanding.

“Together, let’s create a world of acceptance and compassion.”

The pair said their son “joins the unique energy” of a “few dynamic individuals” such as Nikola Telsa, Sir Isaac Newton, Albert Einstein and Michelangelo.

ASD is a neurological and developmental disorder that affects how people interact with others, communicate, learn, and behave, according to the National Institute of Mental Health.

De La Rosa described the diagnosis process as “one of the most challenging years of my life” on her Instagram story.

“Constantly advocating and fighting for answers all while working and trying to be the best mother, friend, and partner,” she said.

In the wake of her son’s diagnosis, De La Rosa said the family altered their Easter Sunday plans to accommodate his sensory needs, hosting a “glow in the dark Easter egg hunt” which he “loved”.
