President Trump offered his first wife the ambassadorship to the Czech Republic and has sought her advice on his Twitter habits, Ivana Trump told CBS News in an interview set to air Sunday.

"I was just offered to be the American ambassador to Czech Republic, and Donald told me, he said, ‘Ivana, if you want it, I give it to you,'" Trump told CBS News. "But I like my freedom. I like to do what I want to do, go wherever I want to go with whomever I want to go, and I can afford my lifestyle. OK, why would I go and say bye-bye to Miami in the winter, bye-bye to Saint-Tropez in the summer, and bye-bye to spring and fall in New York? I have a perfect life."

Ivana Trump, the first of the president's three wives, married Trump in 1977. They had three children, Ivanka, Donald Trump Jr., and Eric, before divorcing in 1992.

In her interview, which will air during "CBS Sunday Morning," Ivana Trump said she still is in regular contact with the president and speaks with him once a week on the phone.

Among the topics of discussion is Trump's frequent use of Twitter, which Ivana Trump said the president asked her about.

"I said, ‘I think you should tweet. It's a new way, a new technology, and if you want to get your words across rightly without telling the New York Times, which is going to twist every single word of yours, this is how you get your message out,'" Ivana Trump said.

Some of the president's critics have chastised his use of the social media site, but Trump has maintained that Twitter allows him to communicate directly to the American people without needing to go through the press.

The president's first wife agreed.

"It's a tweeting president," she said. "This is his new way, how to put the message across, and he's right."
