The former child actor passed away on 10 March, 2010, due to a combination of heart problems, pneumonia and blood flow issues.
Feldman, who first appeared with Haim in 1987's The Lost Boys, burst into tears during the filming of Hollywood Medium With Tyler Henry earlier this month (Aug16), as the medium allegedly made contact with his former best friend.
"I don't feel like his life's story is completely done," Henry told his guest as he channelled Haim.
Now, the late actor's mother has hit out at Feldman, and claims he was only appearing on the show for money.
Judy Haim reportedly told editors at TMZ.com the 45-year-old actor is the last person her son would want to contact, and Haim was trying to distance himself from Feldman while trying to sober up in the years before his death.
Judy said she has repeatedly asked The Goonies star to stop talking about her son and their friendship, and let him rest in peace.
Audrina Patridge, Kris Jenner, Lil Jon, Tori Spelling, and Kendra Wilkinson are also due to appear on the second season of U.S. show Hollywood Medium with Tyler Henry.
