Is another royal baby on the way for Monaco's Andrea and Tatiana Casiraghi?

French news outlets are speculating that Princess Caroline of Monaco could be expecting her fifth grandchild. The royal’s son Andrea Casiraghi and his wife Tatiana Santo Domingo are reportedly pregnant with their third child. Tatiana, 33, and Andrea, 33, who tied the knot in 2013, are already parents to four-year-old son Alexandre Andrea Stefano "Sacha" Casiraghi and two-year-old daughter India Casiraghi.

The family-of-four generally keep a low profile. However earlier this year, Tatiana paid homage to her husband's maternal grandmother, Princess Grace of Monaco, by posing for a Baby Dior photo shoot with her two young children. The relaxed, intimate pictures were taken to honor the luxury childrenswear label’s 50th anniversary, as well as the Monaco royals' late matriarch Grace Kelly.

Ahead of her daughter’s birth in 2015, Tatiana opened up in a rare interview about how being a mother changed her. "There’s so much [that has changed] that I don’t even know where to start, I guess I don’t put myself first any more," the Monaco royal told the website Nine In The Mirror.

When asked about her favorite part of being pregnant, Tatiana admitted, "You feel so complete.” Though she noted, “There’s definitely none of that anxiety you have the first time around, but I am a lot more tired," blaming it on "running around after the first one.”
