Donald first wed Ivana in 1977. During their relationship, they welcomed three children together —Donald Trump Jr., Ivanka and Eric. The former couple was married for more than a decade before their sudden split in 1989, when Ivana learned that Donald had been having an affair with Maples. Their divorce was finalized in 1992.

A year after Donald and Melania said “I do,” they welcomed their first child together,Barron Trump, in 2006. Barron is the youngest of Donald’s five children.
