Former 'X Factor' Star Freddie Combs Dead at 49

Freddie Combs -- the minister who became a fan favorite on the second season of "The X Factor" thanks to his heavenly voice -- has died ... TMZ has learned.

According to his wife Kay ... Freddie died last Friday surrounded by friends and family at a hospital in Florida. She tells us his death was not Covid-related, but the result of kidney failure.

Kay says Freddie was diligently working on his weight loss over the past 11 years -- he had weighed over 900 lbs, getting all the way down to 385 lbs. -- and she's very proud of him. Sadly, she says she knew he was going to pass the day before he did, adding ... "I have so much gratitude to be his wife for 25 years and to be his best friend."

You may recall ... Freddie wowed the judges and audience during his 'X Factor' audition in Season 2 of the U.S. series, as the 540-lb. minister belted out a beautiful rendition of "Wind Beneath My Wings."

Simon Cowell and L.A. Reid promised to back him if he promised to get healthy, lose weight and get out of his wheelchair ... and Freddie vowed to do so.

Though he was eliminated shortly after, his story inspired many folks because he'd already lost more than 400 lbs. since 2009 ... when he topped 920 lbs.

Freddie and Kay, who struggles with weight issues as well, were also featured on a 2010 TLC special called "Ton of Love."

He was 49.
