Nicole Kidman's niece Lucia Hawley is conspicuously missing from the red carpet … Reality star steps in

Lucia Hawley was conspicuously missing from the red carpet at the premiere of “Transformers One” in Sydney on Wednesday evening, just days after the death of her grandmother.

The 26-year-old 7Bravo presenter was nowhere to be seen at the world premiere of the new Chris Hemsworth film after her beloved grandmother Janelle died on Sunday.

Her colleague Bella Varelis represented her that evening and looked absolutely radiant in a figure-hugging black dress as she interviewed 41-year-old Hemsworth.

Nicole Kidman's niece has been keeping a low profile since Janelle's tragic death, after she was seen heartbroken leaving her grandmother's Sydney home just hours after she died at the age of 84.

The daughter of former television presenter Antonia Kidman looked serious as she left the property on Sunday with her long-time boyfriend Henry Poole.

The presenter shielded her eyes with black-framed sunglasses and kept her head down as she exited the property through the front door as the Kidman family held together following the devastating news.

Lucia cut a casual figure in a grey cardigan combined with a white T-shirt and shorts.

She wore a grey outfit and accessorized with a black leather shoulder bag and light brown sandals.

Lucia's mother Antonia was also seen visiting her late mother Janelle's Sydney home on Sunday, bringing a bouquet of flowers from the property.

On Saturday, Nicole announced that her beloved mother had sadly passed away.

The 57-year-old Australian actress had to leave the Venice Film Festival after the devastating news and return to her hometown of Sydney to be with her family.

Her mother Janelle died just hours before Nicole was awarded best actress for her role in “Babygirl” on the last day of the Venice Film Festival.

“Today I arrived in Venice and shortly afterwards learned that my beautiful, brave mother Janelle has passed away,” Nicole announced in a statement read by director Halina Reijn on the occasion of her win.

“I am in shock and have to go to my family, but this award belongs to her. She shaped me, she guided me and she created me.”
