The chairperson of the French global conglomerate Louis Dreyfus Commodities and owner of the Olympique de Marseille football team, Margarita Louis-Dreyfus, is pregnant with twins at 53 years old. The company announced her pregnancy in a statement Monday.

Louis-Dreyfus is due to give birth in early April, but she is planning to "take a brief break and return to work full time in late April," according to Yahoo.

Louis-Dreyfus was married to French businessman Robert Louis-Dreyfus in 1992. He was the former CEO of sports brand Adidas and advertising company Saatchi & Saatchi. They had three sons, Eric and twins Kyril and Maurice. Robert, the cousin of Hollywood actress Julia Louis-Dreyfus, died of leukemia in 2009, according to CBS News.

Swiss tabloids have been following the billionaire's romance with banker and BlackRock investment manager Philipp Hildebrand, but it's not known whether he is the father of Louis-Dreyfus' unborn child, according to the Daily Mail.

Louis-Dreyfus, née Margarita Bogdanova, was born in the Soviet Union in 1962 and came to Switzerland in the '80s. She became a Swiss citizen following her first marriage, but the union didn't last. She met Robert in 1988.

When the latter was diagnosed with a serious illness in 2006, he named Jacques Veyrat as his successor in the family business. However, his wife took the helm as chairwoman and Veyrat left the company.

Her net worth is estimated to be at $6.9 billion, according to Forbes.

Louis-Dreyfus' pregnancy is uncommon as there were only 40 women over 50 years old who gave birth in Switzerland in the last year, according to the Telegraph. Of these women, only nine were pregnant at 53, but the report doesn't indicate if any of the women had twins.
