Bella Kidman Cruise has shared a rare social media update just weeks after her world-famous mother Nicole Kidman made a quick trip to London.

UK-based Bella works as a visual artist in the English capital but is understood to be somewhat estranged from her adopted mother Nicole and father Tom Cruise.

Meanwhile, Nicole regularly shares family snaps with Bella’s half-sisters, Sunday Rose and Faith Margaret, from the Oscar winner’s second marriage to Keith Urban.

In recent months, Bella was noticeably absent from both a mother’s day tribute by Nicole and a group photo of all the Kidman family women taken at the movie star’s Nashville mansion.

Bella also shares another half-sister, Suri Cruise, from Tom’s third marriage to actress Katie Holmes.

On Wednesday, Cruise posted a cryptic Instagram story showing images of two women’s faces spliced together without a caption, marking her first social media update in months.

In 2015, UK-based Bella married British I.T. consultant Max Parker but neither of her famous parents attended the nuptials.

Nevertheless, Cruise reportedly helped pay for the event, while a Kidman source told People that Nicole was “very happy for Bella.”

Nicole was recently in London to appear at the Wimbledon Tennis Championships and attended the men’s singles final with newly retired Vogue editor Anna Wintour.

It is understood Bella, 32, lives in the English capital with her husband but it is unclear if she saw her movie star mother or country star stepfather during the brief visit.

Meanwhile, Nicole’s only son Connor, 30, lives in Clearwater, Florida, a small city closely associated with the Scientology community.

The Aussie movie star has not been photographed with her two elder children in more than 15 years and typically declines to discuss them in interviews out of respect of their religious beliefs.

Tom and Nicole married in a private Christmas Eve ceremony in 1990, less than a year after he finalised his divorce from actress Mimi Rogers.

The pair were married for 11 years and adopted Bella in 1992 and Connor in 1995 before separating in 2001.

Kidman, 58, and Cruise, 63, were reportedly given joint custody of Bella and her younger brother Connor in the divorce.

However, the adopted children, who are devout Scientologists like Cruise, opted to live with their father.
