Louis Dreyfus Commodities has said that its 53-year-old Swiss billionaire chair is pregnant with twin girls.

The conglomerate said in a statement Monday that Margarita Louis-Dreyfus is due in early April and will only take a "brief break" from working before returning full time later that month.

Russian-born Louis-Dreyfus became one of the richest women in the world in the years after she married famous French businessman Robert Louis-Dreyfus in 1992. She subsequently took over his company and the Olympique de Marseille football team on his death from leukemia in 2009.

Louis-Dreyfus' current partner is 52-year-old businessman Philipp Hildebrand.
