Stevie Wonder and the Reverend Jesse Jackson have visited an ailing Aretha Franklin at her home in Detroit.
Franklin's publicist Gwendolyn Quinn told the Associated Press that Franklin's ex-husband, actor Glynn Turman, also visited the Queen of Soul, who is reported to be seriously ill.
The 76-year-old cancelled concerts earlier this year after she was ordered by her doctor to stop touring and rest. Last year she announced plans to retire but said she would perform at "some select things".
Fans, friends and musicians, including Rod Stewart, Mariah Carey, Chaka Khan and Missy Elliott, have been sending good wishes to the singer since the news of her illness broke.
At her concert in Detroit on Monday night with Jay-Z, Beyonce thanked Franklin for her "beautiful music" and said "we love you".
Former US President Bill Clinton tweeted that he and Hillary Clinton "are thinking about Aretha Franklin tonight & listening to her music that has been such an important part of our lives the last 50 years".
Like people all around the world, Hillary and I are thinking about Aretha Franklin tonight & listening to her music that has been such an important part of our lives the last 50 years. We hope you’ll lift her up by listening and sharing her songs that have meant the most to you.

He added: "We hope you'll lift her up by listening and sharing her songs that have meant the most to you."
