Rubicondi is opening a pizza restaurant near Mar-a-Lago

West Palm Beach, Florida (CNN) President Donald Trump has a modern American family tree: a wife, five children from three marriages, two daughters-in-law and a son-in-law, eight grandchildren and two ex-wives.

Family is important to Trump -- made obvious by his clan's frequent presence on the campaign trail, his sons Eric and Donald Jr.'s control of the Trump Organization and his daughter Ivanka's and son-in-law Jared Kushner's playing key roles in the West Wing.

And then there's Rossano Rubicondi, the Italian ex-husband of ex-wife Ivana Trump (one of four), who is launching a pizza place less than four miles from Trump's Mar-a-Lago club in Palm Beach, Florida.

Rubicondi met Trump's first wife and the mother of Donald Jr., Ivanka, and Eric, during the 2004 taping of "Ivana Young Man," a reality special that ultimately aired on Oxygen in 2006. They began dating.
