The former child star was one of the pop star's closest pals 10 years ago, but the pair had a public falling out in 2001 and Feldman further distanced himself from Jackson during his child molestation trial in 2005, when he suggested his relationship with the singer may have been inappropriate.
Now, a week after Jackson's death, Feldman admits he wishes he could have met with his old friend and patched up their differences.
He tells the Los Angeles Times newspaper, "It (Jackson's death) makes you realise that you really have everything you value in life, and every moment and breath. I really learned it’s a bad idea to let unfinished things go unfinished.
"It’s nice to have closure. It’s unfortunate to me that I will never have that closure."
