A SHATTERED family is mourning the death of a ­bubbly young hairdresser who they say was one of three people killed in a horrific CBD car crash.

Northern Beaches woman Bree Keller, 22, has been revealed by her family as the third victim of the crash in inner-Sydney on Saturday morning when a $200,000 Nissan GT-R R35 in which she was travelling left the road and burst into flames after the driver lost control at Darling Harbour.

“She was a lovely, bubbly person ... she was a free spirit and we miss her dearly,” her stepfather Peter Francis said.

“We keep thinking of when she is going to walk in the door ... but she is never going to walk in the door again. Bree was a very attractive girl, both inside and out. She had never been in trouble. She was a delight to be with and had lots of friends.”

Tributes have already started to pour in for Keller this morning.

“RIP Bree, so glad I got to speak to you the day before. Rest easy beautiful. Until we meet again,” Hayden Zuffo wrote on Instagram.

Paige Schmutz wrote: “The last few days have been torture. The world is at a loss without you. I miss you so much beautiful.”

“Absolutely heartbroken! RIP gorgeous girl,” another said.

A police spokeswoman said they were awaiting tests to confirm Ms Keller died in the crash but were confident it was her.

“While formal identification is still to be completed, the woman in the car is believed to be a 22-year-old from Northern Beaches,” she said.

Brothers Steve and Jeff Nasr were also killed in the crash and St Nicholas Antiochian Orthodox Church Punchbowl has been hosting three days of mourning for the pair.

Sole survivor of the crash Joseph Bagala, 39, was pulled out of the car by four police officers before it caught alight.

He remains in a stable condition in St Vincent’s Hospital.

Mr Francis said the family was still trying to work out how Ms Keller came to be in the high-performance vehicle, which had been purchased just six days ­before the crash.

“We have no idea who these people were,” Mr Francis said.

“We knew she was going out, but we didn’t know where, she is 22 years old.”

He said that Ms Keller had only recently returned from a trip around Europe and had been living in the Northern Beaches where she grew up.

“She loved it, she had always wanted to go to Europe and she especially loved London and Santorini,” Mr Francis said.

“She was living at home and doing what kids do.”

He said the family, including Ms Keller’s mother Tania and brother Dion, had enjoyed Father’s Day together last week.

“It was a lovely day, she bought me a lovely present.”

A long-time friend of Ms Keller’s said he only spoke to the 22-year-old on Friday about catching up.

She didn’t say anything about plans to go out that night.

The next day he found out she had lost her life.

“I spoke to her on Friday. She was good saying we’d have to catch up. I hadn’t seen her in a while. We only talked briefly,” Hayden Zuffo said.

“The next day at dinner I got a phone call letting me know what had happened.”

Ms Zuffo said he had been friends with Ms Keller since she was 13 and a student at Mackellar Girls.

He said they had started hanging out with different people but always kept in touch.

He did not know the Nasr brothers in the car with her, or Joseph Bagala who remains in St Vincent’s Hospital.

“She was adventurous and loved to try new things. She was really nice. Everyone loved her, she didn’t have any enemies,” he said.

“She made friends with everyone.”
