Princess Charlene, 44, and her husband Prince Albert were joined by their twin children Gabriella and Jacques to attend church in Monte Carlo for National Day on Saturday.
Monaco s Royal Palace went on to release images from the event, including one which showed Charlene watching over her children as they stood on a balcony.
The mother-of-two, 44, looked sensational in a long-sleeved, floor-length dress which she accessorised with a gold clutch bag as she arrived at the Grimaldi Forum in Monte Carlo.
Camille Gottlieb, whose mother Princess Stephanie of Monaco is the younger sister of reigning Prince Albert, shared snaps of her fun-filled bash on Instagram yesterday.
