"I got engaged last night," the 27-year-old tweeted. "Truly the happiest day of my life."
Ivanka and 28-year-old Jared, the owner of the New York Observer, both come from families who have made their fortune in real estate.
And recently speaking in a magazine interview, Ivanka – the executive vice president of development and acquisitions at the Trump organisation - said she was happy to be in a romance with somebody who shares her lifestyle.
"Jared and I are very similar in that we're very ambitious. That’s what makes it so amazing to be in a relationship with someone who is supportive of that," the New York-born daughter of Donald and Ivana Trump said.
It seems her 63-year-old father is just as pleased about his soon-to-be son-in-law. "I'm very happy about it," the Apprentice star has said. "They make a magnificent couple."
Ivana recently revealed she is studying to convert to Judaism for her fiance.
