Giuliano Zuliani, owner of a local restaurant that Trump frequented, tells PEOPLE she wasn't doing very well when she stopped in with a friend two weeks ago.

"She didn't seem to be in good shape. She could barely walk. She didn't eat her food, she took it home with her," Zuliani says, noting that she remained polite even so.

Prior to her sudden passing, Ivana had been preparing for a summer getaway, her best friend Nikki Haskell told Page Six.

"She was leaving for St. Tropez tomorrow. This was going to be her first trip away since the pandemic. She was afraid of getting the virus," Haskell said on the day of her death.
