"The birth is expected at the end of the year."
This will be the couple's first child together, and the most recent addition to the Grimaldi family.
Prince Albert's niece, Charlotte Casiraghi, welcomed a baby boy in December 2013 with French comedy actor Gad Elmaleh. His nephew Andrea Casiraghi also welcomed a little boy earlier that year.
Almost exactly a year ago, Charlene spoke about her desire to start a family. "Now I'm settled and I think kids will come. I don't put any pressure on myself," she told South African newspaper Sunday World. "If it happens, it happens."
In April, the former Olympic swimmer granted the publication of an exclusive interview in the privacy of the palace with HELLO! magazine's sister publication, HOLA!, in which she spoke of her husband as her "biggest support".
"My husband is my biggest support, the person that I confide in and who knows me best," she said.

She posed for the first time with a very special jewel, the Ocean tiara featuring 850 diamonds and 359 sapphires with different colours all representing the sea foam, given to her by her husband.
In the unique interview, we saw a private and determined side of the blonde beauty. "We must fight for what we believe in, forgive, move forward and not give up," she confessed.
The South African-born royal married Monegasque prince, Albert II, on 1 July 2011.
While this is Charlene's first child, it will be Prince Albert's third. He has previously fathered two illegitimate children, 22-year-old daughter Jazmin Grace Grimaldi, and ten-year-old son Alexandre Coste.
