“I’d like to share a little secret with you,” said a sympathetic real estate agent, played by Marla Maples, in the 1998 movie “Happiness.” “Divorce was the best thing that ever happened to me.”

Ms. Maples herself seems to be thriving since splitting from her ex, now the 45th president of the United States, some 20 years ago.

While raising Tiffany Trump, her daughter with President Trump, as a single mother in California, she made a vibey album with Deepak Chopra and the 14th Dalai Lama and was the host of a radio show on wellness. Most recently, she has had a recurring role as a Christian fast-food proprietor in “The Righteous Gemstones” on HBO.

Ms. Maples, who was Donald Trump’s second wife, remains diplomatic when it comes to discussing the president, declining to answer questions about the impeachment hearings, his tax returns, or his behavior in general. “It is a conscious choice,” she said.
