Finding the perfect name for their little girl was a challenge for Tori Spelling and Dean McDermott, but together, they found their answer. "I used to be obsessed with the book Great Expectations," said Tori. "Estella was the main character. It wasn't fitting, though. And then one day, Dean was like, 'What about Stella?' I said, 'That's it!'" Doreen was Dean's late mother's name.
