Ford has been hospitalized since Sunday and his health has declined ever since.
He is currently on life support and is not expected to make it through the day. Ford's wife, Gina, says the family is still praying for him.
Earlier, Ford's pal, Anthony Anderson, tweeted Ford had died -- but at the time, he was still alive. We're told Anthony had received inaccurate information, and merely tweeted in support of his friend. He's since deleted the tweet.
Tommy starred in all 5 seasons of "Martin" as Martin Lawrence's level-headed best friend, who often played straight man to Martin's crazy antics.
He also appeared on "New York Undercover," "The Jamie Foxx Show" and "The Parkers."
Ford also wrote children's books that promoted drug-free and violence-free lifestyles.
