Amy Winehouse performed at the Nelson Mandela's birthday tribute concert amid her recent health scare.
Amy Winehouse was back on stage in London Friday when she performed rousing renditions of two of her hits at a special concert as part of Nelson Mandela's 90th birthday tribute.
Wearing a white-and-black form-fitting dress, the Back to Black singer, 24, sang "Rehab" and her massive hit "Valerie" for the crowd, who welcomed her with loud cheers.
Despite her recent hospitalization, Winehouse looked healthy. She wore her trademark beehive loose at the back. Decorating her hair was a heart-shaped adornment inscribed with "Blake" for her incarcerated husband, Blake Fielder-Civil.
With Mandela watching in the wings, Winehouse danced while performing "Valerie" and revealed glimpses of her shorts-style underwear. At the end of the song, she made a simple bow of her head, moved back towards the band and thanked the Soweto Gospel Choir.
