Patti LuPone has issued a public apology after more than 500 theater professionals signed an open letter condemning her recent comments about fellow performers Kecia Lewis and Audra McDonald.

Broadway performers and theater professionals are calling on the producers of the Tony Awards to disinvite Patti LuPone from the show after the theater legend made controversial remarks about Audra McDonald and “Hell’s Kitchen” star Kecia Lewis in an interview with the New Yorker.

McDonald had already addressed LuPone’s original comments in an interview with CBS Sunday Mornings, claiming that the two had not spoken in 11 years and she had no idea why LuPone would be upset with her.
