The boyfriend of the young model killed in a fiery supercar crash has paid tribute to "the girl who loved me for my flaws."
Bree Keller, 22, was reportedly one of three people killed when a newly purchased $200,000 supercar burst into flames after rolling off the road in Darling Harbour, Sydney, on Saturday.
Her boyfriend Isaac Treml shared a photo of the couple to his Instagram page on Wednesday, saying Ms Keller taught him "how to be a better dad and to love."
"You showed me what life is really about and most of all you helped my life become so positive with the love you gave me," the father-of-one wrote.
"You're my best friend my love for life and most of all the girl I wanted to grow old with."

A friend of the young model wrote "absolutely heartbroken, RIP gorgeous girl" on her last Instagram post.
Brothers Steve and Jeff Nasr were the other two killed when the Nissan GT-R R35, purchased just six days earlier, went up in flames.
Ms Keller's family said they are still trying to establish how she ended up in the high performance car.
“We have no idea who these people were,” her stepfather Peter Francis told the Daily Telegraph.
“We knew she was going out, but we didn’t know where, she is 22 years old.”
Joseph Bagala, 39, was the sole survivor after he was pulled out of the car by four police officers before it caught alight outside the Novotel Rockford Hotel.
The investigation is ongoing.
