Kecia Lewis, a Broadway vet in her own right who won her first Tony this year as Best Featured Actress in a Musical for Hell's Kitchen, shared an open letter to LuPone on Instagram, in which she called out the Agatha All Along star for a series of "racial microagressions" against the show in recent weeks.

LuPone was captured on video refusing to sign a fan’s ‘Hell’s Kitchen’ playbill because the show was ‘too loud’

"You also, after our sound design was adjusted, sent flowers to our sound and stage management team thanking them." LuPone currently stars alongside Mia Farrow in the Broadway play "The Roommate" at the Booth Theatre,
