The new remarks come after an interview Monday during which Ivana Trump jokingly called herself the “first lady” since she was the president's first wife, a remark that had first lady Melania Trump’s office bristling.

"I have the direct number to White House, but I no really want to call him there because Melania is there,” Ivana Trump told ABC's “Good Morning America” on Monday.

"I don't want to cause any kind of jealousy or something like that because I'm basically first Trump wife,” she continued.

Melania Trump’s spokeswoman slammed the remarks as “self-serving noise.”

“[Melania Trump] plans to use her title and role to help children, not sell books,” the spokeswoman said in a statement. “There is clearly no substance to this statement from an ex. Unfortunately only attention seeking and self-serving noise.”

Melania Trump married President Trump in 2005, his third marriage.
