Earlier this week while Kate stepped out in Grimsby, a fishing port 180 miles north of London, a bystander Sandra Cook claimed she heard Kate almost say she was expecting a baby girl.
But a new video has emerged in which Kate says she will take the teddy bear that was given to her, and asks, "Is this for us?"
When quizzed further down the line by an admirer whether she said "daughter," Kate says that she and Prince William don't know the baby's sex.
"Are you sure?" the woman asks.
"I'm sure," responds an expectant Kate, as Cook laughs. "We don't know. Thank you very much. It's very sweet of you."
