Amy Winehouse has checked into rehab again, her rep confirms. Guess she really is ‘Back to Black.’

The jazz singer “has embarked on a treatment program at the Priory Clinic,” her rep said in a statement. “She wants to be ready for performances in Europe this summer and decided to seek an assessment. She will remain at the Priory on doctors’ advice.”

She was convinced to check into the Priory clinic on Wednesday by her father, Mitch.

“Her dad sat her down and said ‘I think you’re drinking too much again.’ So she agreed to go an assessment to stop it becoming a bigger problem,” a source said.

The same source says the ‘Rehab’ singer also downed a miniature bottle of Smirnoff vodka on her way to the clinic “in typical Amy style.”

Winehouse is set to kick off a mini tour in Europe on June 18, and apparently, she will be out of rehab in time. ”She’s determined, and this is all off her own back,” said the source. “It’s just a lapse. There are ups and downs on the road, and there have been mostly ups recently. But this is a down and she’s done the right thing and gone to rehab.”

I don’t have much hope for her, but at least she’s trying to get on a good path. She’s so talented so I would hate to lost her at such an early age.
