“Lilo & Stitch” star Daveigh Chase grew thinner and thinner throughout her final months struggling with addiction in Skid Row, an outreach worker revealed to The Post.

Kevin Call, who dubs himself the “Mayor of Skid Row,” says he knew Chase — in a much different state than when she was Disney royalty.

“We do outreach, and she used to come through the line,” he told The Post. “But as I see her picture now, and I see what she looked like then…it was a big difference.

“That is what [the] disease of addiction do to a lot of celebrities, a lot of people that end up in this situation here at Skid Row.”

Chase died in a hospital on Tuesday from complications of bacterial meningitis and a blood infection.

Call said he watched as Chase looked thinner and thinner every time he saw her.

“Well, she was getting more thin every time I seen her, she was getting thinner, and that let me know that she had a disease that was unarrested, and she needed help,” he said. “And she couldn’t get the help fast enough before the disease took her life.”

A video taken in Skid Row months before her death showed a severely thin Chase sprawled on the floor of a tent. Friends of Chase told The Post that she was severely underweight at the time of her death.

Call said disease can even take celebrities to dark places on Skid Row.

“People that were well known, and all of a sudden, they turn back, the disease doesn’t care,” he said. “So many start off on a good note, but end up bad, and especially when they have to die in Skid Row.”

Her manager, John Ryan, tried to save her from the infamous addiction-ridden zone, but couldn’t find her in time.

Ryan and Chase’s stepsister had planned to get the actress into a rehab facility in Costa Rica owned by a friend he knew after nursing her back to health in Los Angeles.

“We were so close to finding her,” he told The Post. “Daveigh was the sweetest and brightest light in Hollywood. I can’t believe this is real. Her legacy and work will live on forever.”

Chase’s alleged boyfriend set up a GoFundMe in her name, which her family says is illegitimate. They suspect him of trying to benefit from her name.

She also starred in “The Ring” as horror villain Samara Morgan, and played her final roles in two films in 2016: thriller American Romance and the psychological horror film Jack Goes Home.

Call said that the family could at least find solace in no longer worrying about her horrifying condition.

“I hate to see what happened to her, but hopefully her family will have closure, knowing that they don’t have to no longer worry about her or her condition,” he said.
