'Abbott Elementary' Star Lisa Ann Walter Shares What It's Like Working With Sheryl Lee Ralph

Walter explained that the “Sister Act 2” actor often walks into work with a "monologue or sermon."

School is now in session, and “Abbott Elementary” star Lisa Ann Walter is our instructor.

While making an appearance on talk show “Sherri,” Walter opened up about her friendship with “Abbott” co-star Sheryl Lee Ralph.

“We trade off who comes in being ‘on it,’” Walter told host Sherri Shepherd. “Very often it’s Sheryl being on one.”

The conversation was sparked by a video Walter shared on Instagram earlier this month, while Los Angeles was battling major fires. In the video, the two shared a moment of levity about how the fierce winds driving the flames had left Ralph’s wig “askew.”

“How Miss Sheryl deals with hurricane force winds at 5 a.m.,” Walter captioned her post. “We are so grateful for all the first responders and so deeply sorry for all the loss our neighbors are going through. We are currently between 3 major fires but are safe for now and doing what we do — make things a bit better with laughter.”
