The notoriously private daughter of Cruise and Kidman rarely posts photos of herself on her account – mainly sharing images of her designs, sold on T-shirts, phone cases and prints via her company BKC, which stands for Bella Kidman Cruise.
Along with 25-year-old Connor Cruise, who was adopted in 1995, Bella was adopted by her parents in 1993, and has reportedly had a tense relationship with her adoptive mother since the star couple's highly publicised divorce.
Kidman, 53, and Cruise, 58, separated in 2001 after a decade of marriage, when Bella was just 8 years old.
The exes initially shared custody of their children, however Connor and Bella, both staunch Scientologists like their dad, reportedly turned their back on Kidman after the split.
Kidman, who is not part of the controversial religion, was deemed a "suppressive person", which the church encourages devoted members to 'disconnect' from because they are considered a barrier to spiritual growth.
In actress Leah Remini's memoir, Troublemaker: Surviving Hollywood and Scientology, the former church member recalled being at Cruise's 2006 wedding to Katie Holmes and asking the children if they'd seen their mother recently.
"Not if I have a choice. Our mum is a f**king SP," Bella reportedly told Remini.
Kidman also hinted in a 2007 interview that the relationship was somewhat strained.
"My kids don't call me mummy, they don't even call me mum. They call me Nicole, which I hate and tell them off for it," she said.
However, Connor, who has worked as a DJ, told Woman's Day in 2014 that he still had a relationship with his mother even if they aren't seen together.
"I love my mum," he said. "I don't care what people say, I know that me and Mum are solid. I love her a lot. My family means everything. Yeah, I love my music, but the family comes before everything else."
Bella also rubbished estrangement rumours in 2016, telling New Idea: "Of course [we talk], they're my parents", adding that anyone who believed the whispers was "full of sh*t".
Bella married IT consultant Max Parker in a secret ceremony in 2015, which neither Cruise or Kidman attended.
Woman's Day later reported that Kidman met her daughter's husband for the first time almost a year after they got married.
Over the years, the Big Little Lies star has remained largely silent about her strained relationship with her adopted children.
"I'm very private about all that. I have to protect all those relationships. I know 150 per cent that I would give up my life for my children because it's what my purpose is," she previously told Who magazine.
Following her divorce from Cruise, Kidman welcomed another two daughters, Sunday, 12, and Faith, 9, with her second husband, country singer Keith Urban.
