Amy Winehouse has once again checked into rehab. The singer has entered a treatment program at the Priory Clinic in London at the urging of her father. According to a statement released to People by her representative, Winehouse "wants to be ready for performances in Europe this summer and decided to seek an assessment."

Another source close to Winehouse told People that the singer drank a miniature bottle of Smirnoff vodka on the way to the clinic, which is a sign that this new round of treatment might be a pretty good idea. Winehouse is set to kick off a leg of concert dates in Europe on June 18th.

Winehouse has reportedly been at work on a followup to her 2006 breakthrough album Back to Black – there was word that she recorded a duet with Cee Lo Green back in January – but so far there it is unknown whether any of this new music will hit stores any time soon. Winehouse's most recently released performance was a cover of Lesley Gore's "It's My Party" recorded for Quincy Jones' 2010 album Soul Bossa Nostra.
