Amy Winehouse left the hospital on Friday looking much, much healthier than usual. However she’s already back. It’s unclear whether that’s because her health is still up in the air or because she’s being diligent and actually trying to get better – People claims it’s just because she’s in “ongoing treatment.”

After a weekend at home, Amy Winehouse has returned to the hospital for ongoing treatment. The 25-year-old singer, whose well-documented substance abuse has triggered a string of medical interventions, spent the past week being treated at the London Clinic. She left the hospital on Friday, but checked back in Monday.

“She had a chest infection [last week] and underwent some tests to make sure nothing else was wrong,” a source tells PEOPLE. (Earlier this year, doctors diagnosed the Grammy-award-winning chanteuse with scarring of the lungs.)

Is Winehouse finally committed to getting healthy? “She has been told to give up smoking and was initially struggling with that – she was covered in nicotine patches at one point,” says the source. “But she is making an effort.” The notoriously skinny singer was photographed looking somewhat fuller in the face last weekend – a healthier look that won praise from two British tabloids.

Winehouse’s London rep said that she’s been working on her next album from her home and has even been learning how to play the drums. I’m sure her neighbors love that. According to The Sun, Amy cancelled her Halloween gig, but probably not out of her usual drug-induced haze. She released a statement that made it sound like she’s working on staying away from temptation and getting better.

AMY WINEHOUSE is determined to kick her drug and booze addictions once and for all – telling fans “I’m getting better”. So much so, she even missed the chance to party with pals at a debauched Halloween bash. Junkie Amy was on board to DJ at the A Plague On Both Your Houses event in London but pulled out in a bid to steer clear of temptation.

She apologised for her no-show, hinting that she’s well and truly on the path to recovery.

In a statement, she said: “This goes out from beyond the grave. I’m getting better so I’m not undead, but you guys enjoy the afterlife.”

Well that was a little dark and Halloween-y, but appropriate nonetheless. Amy’s friends are worried her health has deteriorated so severely that her career is over. Her frequent chest issues are obviously a really serious problem since she needs strong lungs to record and perform.

Friends fear the singer, who was hospitalized last weekend with a chest infection, has damaged her voice through partying and may never record another album.

Record bosses allegedly claim work on the follow-up to her award-winning “Back to Black” album is “going slower than hoped” because of her health problems.

However a spokesperson for the star insisted there was no need to worry. “Amy isn’t on a deadline with her album,” he said. “She’s in and out of the studio working. Amy’s fine.”

Amy’s number one priority should be getting better, and the career stuff should come after that. Though certainly they’re intertwined. It seems like she realizes how far she’s fallen and just how lucky she is to still be alive. Considering how much better she looked in photos last week, it seems like she must be doing something right. There’s been speculation that she’s at the London Clinic not due to chest issues but for rehab. It could be both. It seems like Amy has an appreciation for what she needs to do to get better, and now she’s actually starting to do it.
