The 23-year-old, who will compete in next Sunday's final alongside Sam Attwater and Laura Hamilton, told Hello that Richard Madeley and Judy Finnigan had "helped" her through difficult times during her teenage years.
"I feel so happy and warm inside that I've made my parents proud," she said in an interview with the magazine.
"There have been times when my parents could have gone really mad but they've illustrated to me that it was a mistake in some way and also helped me through it.
"With the exception of the car accident, which was a gross misjudgment on my part and something I really regret, everything that labeled me a wild child was pretty much standard behaviour for a young girl in London."
She added: "Aside from the whole Richard and Judy fame thing, I am incredibly lucky they're my mum and dad."
