The 'Rehab' singer, who has made frequent trips to hospitals following her drink and drug addictions, had reportedly collapsed with a seizure and hurried to a London clinic following a heated argument with her hubby over the phone.
"They had a screaming row. She was beside herself after the call - and she just totally lost it," the Sun quoted a source as saying.
"She has ended up in hospital a few times after similar drink and drugs related seizures. If she carries on, one of these incidents will be her last," the source added.
Though the songwriter's rep confirmed Amy's recent hospital visit, he claimed the cause to be "a bad reaction to the combination of medication she has currently been prescribed."
The 'Back To Black' hit maker, who is said to be paying Blake's 32,000-pound rehab bill for his drug addiction, was allegedly "getting her life back together" while Blake was still in jail for assaulting a pub lord and trying to cover up his act.
