Former U.S. President Donald Trump made the announcement of Ivana Trump's death on social medial platform Truth Social.
"I am very saddened to inform all of those that loved her, of which there are many, that Ivana Trump has passed away at her home in New York City," Trump said in a post.
A former model who once trained for the Czechoslovakian junior national ski team, Ivana Trump played a role in building up the Trump media image in the 1980s. She also helped her husband build some of his signature buildings including Trump Tower.
The couple married in 1977 and divorced in 1992. They had three children together: Donald Jr., Ivanka and Eric.
"Ivana Trump was a survivor. She fled from communism and embraced this country. She taught her children about grit and toughness, compassion and determination," the Trump family said in a statement.
Neither the Trump family statement nor the post from the former president mentioned the cause of her death.
