Malcolm-Jamal Warner, who many of us remember as Theo Huxtable from The Cosby Show, has sadly passed away at the age of 54.

TMZ was the first to share the news, reporting that he died from an accidental drowning. While this is heartbreaking, it’s been confirmed by a source, the actor was on a family vacation in Costa Rica and drowned while swimming.

Warner had a rich and varied career in television, starring in shows like Malcolm & Eddie and voicing The Producer on The Magic School Bus. Beyond acting, he was also a gifted musician, earning a Grammy in 2015 for Best Traditional R&B Performance.

He leaves behind his wife and daughter, and it’s worth noting that he mostly kept his personal life private.

His contributions to entertainment as an actor, poet, musician, and storyteller will surely be remembered fondly by fans and colleagues alike.
