Speaking to PEOPLE in April, Frankel shared details about how Bernon popped the question.

"It was intimate," she recalled of his February proposal. "Just the two of us, on an island off of Florida. No makeup, no manicure, no ring photos. It was very simple and beautiful."

She also dished on meeting her beau on an app, teasing that he came "better than advertised."

"I was pretty lucky when I walked in and saw him," Frankel said. "He had a twinkle. He came as advertised — better than advertised. He overshot the mark."

She added, "Paul's an absolutely beautiful person and it's an exciting, fun time."

The following month, Frankel and Bernon took their romance abroad to celebrate the Fourth of July in Lake Como, Italy.
