STUBBORN TANYA BATTLING FOR EVERY LAST BREATH!

FEARS for country hellraiser Tanya Tucker have spiked as insiders say the bullheaded Delta Dawn singer is suffering from such severe bronchitis that she needs an oxygen tank to breathe and she refuses to change her ways!

- 

"She needs to be administered oxygen at least a couple of times a day," dishes an insider, who adds the 65-yearold's years of partying have left her a physical wreck.

"She still drinks and smokes to the point where it frightens people around her, and now she's suffering from crippling tremors!"

The source claims pleas from loved ones to change her ways have fallen on deaf ears.
