The Wedding Crashers star admits she was initially devastated when she realised Father Christmas was a holiday myth - but she quickly caught on to the fact that she no longer had to write to the North Pole every year.
She tells WENN, "I was six when I stopped believing in Santa. My brother broke it to me along with the tooth fairy not being real at the same time. It was a massive blow.
"I actually remember feeling very betrayed by my parents. But I was at least able to beg them more openly for the stuff that I wanted the following year."
