Monaco's ruler Prince Albert and his wife Princess Charlene are expecting their first child.
"The prince and the princess of Monaco are delighted to announce the pregnancy of ... Princess Charlene," a royal announcement said. "The birth is expected at the end of the year."
The couple married in July 2011 in an opulent ceremony in the Mediterranean principality, stomping ground of the rich known for its Grand Prix car race.
Prince Albert is the son of the late Prince Rainier III and actress Grace Kelly, who set aside a career in Hollywood to become Princess Grace but died after a car crash in 1982.
Before her marriage into the ancient House of Grimaldi, whose family members have ruled Monaco since 1297, Charlene Wittstock was a national champion swimmer from South Africa.
The couple met when Albert presided over a swimming race in 2000 in which Wittstock was competing.
The royal family has been in the news most recently over the film that kicked off the Cannes Film Festival this month, Grace of Monaco by French director Olivier Dahan.
The film starring Nicole Kidman as Grace Kelly was derided by Albert and his two sisters, Princess Caroline and Princess Stephanie, as "a farce" based on "erroneous and dubious historical references".
