The 69-year-old soul legend and Grammy award-winner said she was hoping to marry over the summer.
She told AP that she and Mr Wilkerson were considering Miami Beach, Florida, as a possible location, followed by a reception on a private yacht.
Franklin, whose latest album is called Aretha: A Woman Falling Out of Love, has been married twice before.
"We're looking at June or July for our date, and no, I'm not pregnant, LOL!," she said in a statement.
The singer returned to performing in May last year after being admitted to hospital for an undisclosed ailment.
