Forget William and Kate — New York has its own royal romance.
An affair between downtown moneyman Christopher O’Neill and his uptown girl — the gorgeous Princess Madeleine of Sweden — has become the hottest gossip of Stockholm’s long, cold winter.
O’Neill, a 36-year-old millionaire who dispenses financial advice to super-wealthy clients, is “in a love affair” with his 28-year-old Swedish dish, a source close to the couple told The Post.
A Spanish tourist armed with a cellphone took a video of the lovebirds at the Central Park Boathouse that has become an Internet sensation in the Nordic nation. Madeleine, the height of style in a white fur vest, is seen affectionately rubbing O’Neill’s arm.
“She is always happy when she is with him,” the source said.
Madeleine, a k a the duchess of Hälsingland and Gästrikland, is the daughter of King Carl XVI Gustaf and Queen Silvia.
O’Neill’s family also has a regal connection — his mother, Eva, has dated Prince Charles, according the Swedish tabloid Aftonbladet.
While Madeleine’s romance has flown under the radar here, pictures of O’Neill with gorgeous women — in one 2008 photo he is seen posing with lingerie model Maryam Abdullina on a yacht — appear occasionally on society Web sites.
