Le cœur a ses raisons (The heart has its reasons) is a French-language Québécois téléroman which heavily parodies American soap operas, often involving great exaggeration to ridiculous proportions. The English translation of its title is The Heart Has Its Reasons, but its distributor chose to release it as Sins of Love. The title comes from Blaise Pascal, a 17th-century French author, who wrote, « Le cœur a ses raisons que la raison ne connaît point » ("The heart has its reasons that reason does not know"). It was written by author Marc Brunet and first appeared on television screens in February 2005 on the TVA television network.

The program was first shown in September 2001 as short segments during the show Le Grand Blond avec un show sournois, and became very popular, thus making way for a full television series. There were 17 short episodes preceding the first series.

The program airs internationally on TV5Monde. A Polish version of the show, entitled Grzeszni i bogaci (The Sinful and the Rich), premiered on October 25, 2009 on TVN television network.
