Singer Natasha Bedingfield brought the Billboard Music Awards audience to its feet in Las Vegas on Sunday night (20May12) when she paid tribute to Donna Summer by performing the late disco diva's signature tune Last Dance.
Backstage, after the emotional performance, Bedingfield revealed she and Summer were friends and she is still coming to terms with her death.
The pop star says, "I was very emotional out there because I knew Donna Summer and we didn't know she was ill.
"It was so precious to me. It felt so important to me that we should honour her. She was a very kind woman... and she brought love and light to people."
Summer lost her secret battle with cancer last week (17May12).
