Amy Winehouse is not in rehab – despite reports circulating Tuesday that she's finally seeking treatment, a rep for the singer tells PEOPLE.

"Amy is not in rehab," the rep says. "She was seeing a doctor who she regularly sees as part of her ongoing treatment. It was a regular appointment which she attends all the time. She has not checked in overnight."

The rep would not comment on the nature of the treatment.

The reports followed a shocking video posted by the U.K.'s The Sun newspaper allegedly showing the singer smoking crack.

Meanwhile, those close to her agree that she needs help.

"It's really sad. Everyone knows she needs help – even she knows she needs help," a friend of Winehouse's who is in the music business told PEOPLE Tuesday. "The video is horrible but I hope it forces her to do something."

Whether the tape will finally prompt the "Rehab" songstress, 24, to rehabilitate herself remains to be seen. "I've lost count of how many times rehab has come up. You can't bring it up to her – she has to want to try and she just doesn't seem to," the friend added.

The videotaped incident allegedly was recorded just hours before Winehouse attended a court hearing for husband Blake Fielder-Civil, 25, who is awaiting trial on assault and conspiracy charges.

"People are tiptoeing around her because of Blake – it's like someone died," the friend said. "She's so crazy about him. When he first went to jail she couldn't function. She didn't know what to do with herself."

Her label, Universal Records, said in a statement, "We are deeply disappointed and upset by these latest revelations and are doing everything we can to offer Amy our full support in dealing with her problems."
