Liza Minnelli — New Health Fears As Stressed Star Worries Over Sister

Word that singer Lorna Luft suffered a frightening collapse backstage at a London concert — and shocking brain-tumor diagnosis has gutted sister Liza Minnelli — and left friends fearing for both sisters!

“Liza and Lorna have grown close in recent years after years of feuds,” a source exclusively spilled to The National ENQUIRER. “Lorna’s cancer battles brought them back together, but now Liza is terrified she may lose her sister forever!”

Lorna seemingly beat breast cancer in 2013 and reunited with Liza — following years of arguments over the “Cabaret” star’s self-destructive drug use! “Now Liza is terrified that she will lose her little sister after all those lost years they were at odds,” the insider claimed.

Worse yet, the source said friends are worrying Lorna’s health woes will cause Liza to relapse! “Everyone is worried that Liza won’t be able to handle it if she loses Lorna,” the source added.
