Flo Rida has spoken up about his sadness after Donna's death. He said he was inspired by her music, explaining he used to listen to her tracks.
'I was just looking at something with er months ago,' he told MTV News. 'When I got a text message about her death, I though 'Who, she passed away.' She definitely is one of those iconic peple when it comes down to the dance scene and all that. 'My condolences go out to all her family. She definitely influenced what I do.'
KC and the Sunshine Band star KC 'real name Harry Wayne Casey' was devastated to hear about Donna's passing. He saw her several months and had no idea she wasn't well. "She looked great. I'm sure if there was anything going, she wasn't about to share it with anybody outside of her immediate family," he told ET Online.
Other stars to pay tribute to the singing superstar include Dolly Parton, Kylie Minogue and Sir Elton John.
Donna's fans gathered at her star on the Hollywood Walk of Fame, where flowers have also been laid in her honour.
