Cara has been starring in musical Cabaret in the West End and wants to take it to New York.
She said: “Broadway would be a dream. I’ve caught the theatre bug.
“I’ve had some personal things happen in my life but I go on stage and forget about all of it.”
Tragically Cara’s £5million mansion burnt down in a catastrophic fire while she was across the ocean in London.
The actress’ mum said Cara was devastated after “her whole life” was destroyed in the blaze.
The heartbroken star shared a sweet picture of her two cats, writing that her heart was “broken” and telling fans to “cherish what you have” when she thought they had perished.
She later shared an adorable picture of the pair, writing: “THEY ARE ALIVE!! THANK YOU TO THE FIREFIGHTERS.”
