Oprah Winfrey looked thinner than ever backstage at the 78th Annual Tony Awards, which were held at Radio City Music Hall in Midtown Manhattan on Sunday.

LuPone called her “bitch” in the New Yorker. She also took aim at six-time Grammy winner Audra McDonald, who was nominated but did not win on Sunday, for supporting Lewis’ remarks. LuPone said it was “typical” of McDonald and that she “was not a friend.”

LuPone, 76, went viral last month for making nasty comments about fellow actress Audra McDonald before apologizing for her “bullying” behavior.
