Ivana Trump made a surprise appearance on the Italian Dancing with the Stars Saturday. She danced alongside ex-husband Rossano Rubicondi for the ninth episode of the series, which is called "Ballando Con Le Stelle" in Italian.

Ivana, 69, wore a red see-through dress. She practiced with professional dancer Samuele Peron, who escorted her out on the stage and handed her off to Rubicondi. She was met with applause from the audience and performed a waltz.

Some might have been shocked by Ivana's appearance on the reality show. Ivana, the first wife of President Donald Trump, appeared on the series less than a year after she slammed Trump's second wife Marla Maples for appearing on Season 21 on the reality competition in her 2017 book, Raising Trump. Maples was married to the president from 1993 to 1991. Ivana was married to Trump from 1977 to 1992.

"No class!" the former professional skier wrote. "I wouldn't go on that show, dancing in those tiny dresses with the boobs and butt hanging out."

Maples, who danced with Tony Dovolani, was shocked when she was eliminated from the series. "I have to say, for the first time in 21 seasons, I did not expect this at all," Dovolani said on Good Morning America at the time. "We had such a great journey, she was growing every single week, it felt like she was really hitting her stride."

Maples was "stunned" they were kicked off. "Truly, my heart's broken. I love the show," she said. "I've had a rough few years, and this helped me learn how to not just walk again but learn how to dance. So I really hoped to continue and I hoped we could just keep sharing the fun."

She enjoyed her time with Dovolani, calling him "the greatest teacher." Competing on DWTS was "the hardest work I've ever done," she said.

Maples' daughter, Tiffany Trump, was proud of her mother for competing. "She's extremely sad that we're not still in 'cause she knows how much this means to me and to Tony, and she knows how hard we worked," Maples said. "I mean, we worked so hard! We gave everything. But she's going to be alright. She's proud of her momma, and that's what you want your babies to be. You want to inspire your children, and I'm so grateful for all the women and daughters that have been so supportive and I just hope we can keep inspiring each other."

The U.S. version of Dancing with the Stars is airing its first-ever athletes edition for Season 26. Stars like former figure skater Tonya Harding, former basketball player Kareem Abdul-Jabbar, and figure skaters Adam Rippon and Mirai Nagasu are competing for the Mirror Ball.

Dancing with the Stars: Athletes airs Mondays at 8 p.m. ET on ABC.
