The 'rehab' singer has another good night!

Fresh off her Grammy sweep, troubled "Rehab" singer AMY WINEHOUSE enjoyed another successful moment at the Brit Awards in London as she took the stage and received the biggest crowd reception of the evening.

Despite her famous song about saying "no, no, no" to treatment -- Winehouse seems to be doing better after a stint in rehab just weeks ago. She performed the hit "Valerie" with MARK RONSON, and gave another shout out to incarcerated hubby BLAKE FIELDER-CIVIL.

Winners of the night included a present PAUL McCARTNEY with the lifetime achievement award, THE FOO FIGHTERS, KYLIE MINOGUE and KANYE WEST. OZZY OSBOURNE and family hosted the show.
