Frankel was seen Thursday enjoying a holiday in Saint-Tropez with longtime confidant and hedge-fund mogul Warren Lichtenstein.
Frankel, 42, looked cool and chic on her trip in platforms, a short skirt and tank top. She walked side by side with Lichtenstein, a billionaire from New York, who is the chairman and CEO of Steel Partners Holdings L.P.
"They are friends and nothing more," a source tells PEOPLE.
He has reportedly opened his Upper East Side apartment to Frankel and has been a constant support as she continues a tough divorce from Jason Hoppy, whom she married in 2010 and is father to Bryn, 3.
