It would seem that Donald traded in Ivana for a younger model, Marla Maples since he started having an affair with Marla who it is claimed he met at church while still married to Ivana, leading to a scandal and tabloid feast, followed by a contentious and costly divorce for Trump.
After he married Maples, Trump said in an interview with Esquire magazine:
That marriage didn't last long however and it has been said it was because Maples didn't like the time Trump spent working instead of with her and their daughter Tiffany.
Then again Ivana seems to have her own issues since she was married once before marrying Trump and married twice after.
