Michelle Williams is stepping down from her role in a new Broadway musical. Playbill confirmed the 38-year-old singer and actress will take a hiatus from the Broadway production of "Once On This Island." "Effective immediately, Michelle T. Williams has been advised by her doctors to take a leave of absence from performing," the show said in a statement Wednesday, according to People. Williams debuted as the goddess Erzulie in "Once On This Island" on Nov. 30. Cassondra James will replace Williams in the role through Dec. 26 before Lea Salonga takes over until the musical closes Jan. 6. News of Williams' departure follows word of her split from her fiance, pastor Chad Johnson. Williams said in a since-deleted post last week that she and Johnson had called it quits. "I still remain fearless," the star said. "I guess I 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," she added. The former Destiny's Child singer sought help for mental health issues earlier this year. She told fans in July she was feeling happy and healthy after working with healthcare professionals on her well-being.
