Cher Health Crisis As She Grieves For Ex-Husband

Friends of Cher — who is still grieving over ex-hubby Gregg Allman's death by liver cancer last year — fear the singer's sorrow and stress will trigger a relapse of the life-threatening Epstein-Barr virus that almost killed her!

“Cher is shattered,” a source says. “She’s already pushing herself to the limit with her concert series in Las Vegas — this endless grief may break her.” Cher bared her heartache in a series of early morning tweets the day after what would have been Gregg's 70th birthday.

“Lying here Listening 2 Gregory sing ‘Song for adam’ & Crying. His Voice still has that effect on Me,” she wrote of the rocker who fathered her son Elijah Blue (left, in 2002). “Haven’t been able to listen to ‘Laid Back’ all the way through & Can Only listen to ‘Southern Blood’ One Track At a Time.

“My heart breaks Every Time He Sings, but (praying). “His Voice is still there (applause).” Gregg's label released "Southern Blood" in September, four months after his death.

“Gregg’s womanizing, boozing and drug abuse ripped apart their marriage, but Cher continued to love him,” The National ENQUIRER learned from an insider. “She thought Gregg beat liver cancer with a 2010 transplant — and didn’t know the deadly disease returned two years later.

"He kept the diagnosis secret so he could keep playing music until the end. It came as a huge shock when Cher found out last year. She reached out offering her support in his last days, but his death made her realize she, too, is hurtling towards her final curtain.

“She’s undergone cutting-edge treatments in Germany in a desperate bid to stop the virus that’s left her bedridden for months, fighting for life," the insider said. “But experts say high stress can trigger the virus — and at 71, we fear the worst for Cher.”
