Jackie Kennedy's Husband Aristotle Onassis Initially Dated Her Sister

While Jackie Kennedy may have been smitten with the dark-haired shipping magnate, some suggest his attraction to the former First Lady was simply a business deal. Author J. Randy Taraborrelli told People, "I think from [Aristotle] Onassis' point of view, it was an acquisition." He didn't deny that Aristotle may have loved the American socialite but that they weren't in love at the time.

Perhaps Jackie felt similarly, as she reportedly said he "rescued [her] at a moment when [her] life was engulfed in shadows" (via The Washington Post). This sounds romantic until you hear that even Jackie's confidante and live-in assistant told Fox News that they "seemed like friends, not a couple." And we now know that being wealthy might have been the main deciding factor for Jackie on whether or not to stay with a man.

In all, it seems like Jackie went through quite the trauma with the devastating death of her husband. As a result, she decided to place her trust in a close (well-off) friend who offered security for her and her little kids. In her honeymoon photos, showing her swimming in the Grecian waters near her husband's yacht, was she smiling because she was head over heels in love or relieved to not have to fend for herself? Who knows. But we can say that sister Lee Radziwill seems to have gotten the bad end of the deal.
