Crown Princess Maxima — Willem-Alexander, the heir to the Dutch throne, was once known as "the Prince of Fun." When he met Argentinean Maxima Zorreguieta, he decided to settle down. The hitch: Her father had been a member of Argentina's former junta, a repressive regime blamed for torturing and killing thousands. The solution: Maxima distanced herself from her dad, who wasn't invited to the wedding. In December 2003, the crown princess gave birth to an heir, Princess Amalia.
Mabel Wisse Smit — The Dutch government decided to accept Willem-Alexander's chosen bride, but they weren't so accommodating when it came to his younger brother's romance. Prince Johan Friso, the second of Queen Beatrix's three sons, had to renounce all rights to the throne when he married Mabel Wisse Smit, a human rights activist, in April. The couple acknowledged that, during the vetting process, they had misled the government about the extent of Wisse Smit's past relationship with a drug lord. Johan Friso gets to keep his title of prince, but his wife remains a commoner.
Princess Stephanie's Spouses — Even princesses have to kiss more than a few frogs. Monaco's "wild child" princess was traumatized by the 1982 death of her mother, former movie star Grace Kelly, in a car crash. Since then, she's made some questionable life choices. She married her former bodyguard, Daniel Ducruet, after the births of their two children, Louis and Pauline. But the marriage didn't last long; Ducruet was caught on camera cavorting with a lady who had been crowned Miss Topless Belgium. In 1998, the divorced Stephanie gave birth to a daughter, Camille Marie Kelly, whose father she has never revealed. Then the princess ran away with the circus, or rather, a circus ringmaster. Her romance with Franco Knie, a Swiss circus director and elephant trainer, didn't last, but Stephanie remained smitten by the big top. In 2003, she married Adans Lopez Peres, a Portuguese circus acrobat. The acrobat, described as a juggler and handstand expert, has not received a royal title.
