Aretha Franklin says that she’s thankful for prayers from well-wishers in a statement released Thursday (Dec 2) following a recent “highly successful” emergency surgery. The statement, however, didn’t mention why she needed surgery.

“God is still in control. I had superb doctors and nurses whom were blessed by all the prayers of the city and the country,” the statement read.

Last month, Aretha Franklin announced that she was canceling all upcoming concert dates and appearances through May, per doctor’s orders. That particular announcement came after Franklin briefly paid a visit to a Detroit hospital, though no details were given about her condition at the time.
