Omarosa Manigault Newman is following up her year in the White House with a stint on "Celebrity Big Brother."

CBS unveiled the cast of the reality show's upcoming season Sunday with a commercial that aired during the Grammy Awards.

Besides Manigault Newman, contestants include basketball star Metta World Peace and actresses Marissa Jaret Winokur and Keshia Knight Pulliam.

Manigault Newman previously appeared on "The Apprentice." She most recently worked as an adviser to President Trump.

Her December White House departure became somewhat controversial. With it, the White House lost arguably its most prominent and visible African-American senior staffer, serving as a reminder to some of the lack of diversity at the upper echelons of the Trump administration.

Manigault Newman was one of just a handful of African-Americans to hold a senior position under President Trump. Ben Carson, the secretary of Housing and Urban Development, is the president's only African-American Cabinet member. Jerome Adams, President Trump's surgeon general, is also black.

In an interview at the time with ABC's "Nightline," Manigault Newman said she often felt lonely as "the only African-American woman in this White House."

"At times it was very difficult," she said, recalling sitting in morning senior staff meetings, with 30 other assistants to the president, where nobody looked like her.

"There was a lack of diversity that I will acknowledge," she said in the interview. "And at times it was very lonely. Because the majority of them were white men who had their own agendas. Many of them had never worked with minorities, didn't know how to interact with them."

White House spokeswoman Sarah Huckabee Sanders insisted to reporters Thursday that the White House staff was indeed diverse, despite evidence to the contrary.

"Look, we have a really diverse team across the board at the White House," she said, adding, "We always want to continue to grow the diversity here. We're going to continue to do that and continue to work hard. "
