It's nice to know some things never change.
British trainwreck Amy Winehouse was an hour late to her first post-rehab concert Friday night. The Grammy-winning soul chanteuse performed a 55-minute set at the sold-out Rock in Rio music festival in Lisbon, Portugal. Lenny Kravitz was the headliner.
Winehouse's voice cracked throughout her performance and, at one point, she ran offstage. She had visible cuts on her left arm, a bandage on her right hand and apologized to the crowd for her sore throat.
The trouble-prone diva is famous for her tardiness, show cancellations, offstage antics and rehab stints. Just last week, her father accepted a prestigious British award on her behalf because the 24-year-old was late to the ceremony.
In Amy's defense, they don't teach punctuality in rehab.
