In the past Tatiana has said she doesn't particularly enjoy being photographed, but this week she looked happy and relaxed, flashing a sweet smile at the camera.
Just before Christmas the proud father and mother showed off Sacha for the first time at the Monaco National Day celebrations. With his curly blond hair and chubby face, the youngster bears a strong resemblance to Andrea when he was little.
It's an exciting time for the reigning family of Monaco. Prince Albert and wife Princess Charlene have just had twin babies, Jacques and Gabriella.
Meanwhile, Andrea's brother Pierre Casiraghi is engaged to his Italian girlfriend Beatrice Borromeo. Their wedding is set for 20 April.
