CHER ROCKED BY BIPOLAR BOMB!

Daughter-in-law drops legal dime on shattered diva

- 

CRUMBLING Cher is suffering manic depressive episodes, according to insiders who insist her brutal legal war over son Elijah Blue Allman has plunged her into a tragic downward spiral that's destroying her health and her life.

Sources close to the struggling 77-year-old songbird confirm she's trapped in a living hell as she fights to save her 47-year-old son from drugs while also locking horns with his wife, Marieangela "Queenie" King, who told a judge Cher suffers from bipolar disorder.

In a bombshell filing challenging Cher's bid to have Elijah placed in a conservatorship, the 36-year-old claimed her estranged mom-in-law has admitted being a "manic depressive" and is not capable of managing her own affairs, let alone her son's.
