Michelle Williams has revealed that her engagement to pastor Chad Johnson is off.

The 38-year-old Destiny’s Child singer made the announcement in a since-deleted Instagram Story post on Friday morning — the same day she dropped her latest single, “Fearless.”

“I still remain fearless,” she wrote in simple white text on a black background. “I guess I still remain single! Things didn’t work out. The healing that needs to take place is a must! I don’t wanna destroy another relationship. Blessings to him, his family and ministry. #FEARLESS”

Reps for Williams didn’t immediately return PEOPLE’s request for comment.
