Princess Charlene returned home on Sunday evening after spending months away from her twins, Prince Jacques and Princess Gabrielle, as well as husband, Prince Albert.
The royal contracted an ENT infection in May and has been recovering in South Africa following multiple complicated procedures.
The former Olympic swimmer said, before her departure: "It's been, obviously, a very challenging time to be here, but at the same time, it has been wonderful being back in South Africa."
She's since taken to Instagram to share a sweet photo with her family.
"Happy day today," she wrote as she held Albert close, despite ongoing rumours of the couple's split. Their two children stood before them in the sweet pic.
"Thank you all for keeping me strong !! [sic]" she said.
