Nicole Kidman has made her return to social media to mark Paris Fashion Week

The Practical Magic and Moulin Rouge! star posted a series of images on Instagram on Tuesday (0.10.25), showing her attending the Chanel presentation alongside filmmaker Baz Luhrmann and French singer Vanessa Paradis.

Nicole, who is an ambassador for the brand, appeared relaxed in a white button-up shirt and jeans, debuting a new haircut she described as part of her "breakup bang" era.

She captioned the photos: "Thank you @chanelofficial for having me and my girls (red heart emoji.)

"So excited to be a part of it with you @matthieu_blazy."

The actress was joined at the show by her daughters, Sunday Rose, 17, and Faith Margaret, 14, though they were not featured in her post.

Nicole also reshared a clip from hairstylist Adir Abergel, who wrote on Instagram: "New bang era," while showcasing Nicole's updated look.

The appearance marked Nicole's first major public outing since filing for divorce from Keith after 19 years of marriage. According to court documents obtained by Page Six, she cited "irreconcilable differences" as the reason for their split. Nicole has requested to be the "primary residential parent" of the couple's two daughters.

Insiders told Page Six the Babygirl star had tried to salvage the marriage but is now focused on moving forward.

A source said: "She was sad, but moving on.

"Sometimes relationships just run their course."

Reports from TMZ claimed Nicole and Keith had been living separately in Nashville since early summer.

Keith, currently in the middle of his High and Alive World Tour, appeared without his wedding ring during a public appearance last week.

The country singer, known for hits including Fighter, was photographed en route to his concert at the Giant Center in Hershey, Pennsylvania, where he paid tribute to Nicole and their daughters with a series of on-stage images.

He and Nicole married in 2006 and have long split their time between the United States and Australia.

Their separation was finalised on 30 September, with both parties said to be focused on co-parenting their children while continuing their professional commitments.
