Kidman recently flew to Australia to begin production on her upcoming TV series Nine Perfect Strangers. The family reportedly quarantined -- per Australia's health and safety protocols -- at their home in Australia's Southern Highlands for two weeks before she was able to see her mom.
Kidman might not have been with her mom for her 80th birthday this year, but she did celebrate it back on March 12 with a sweet mother-daughter snapshot and a kind message.
"Happy Birthday to my darling Mumma. I love you so much. This photo is so US! ? ❤️ ?" Kidman captioned the cute pic.
