THE Duchess of Cambridge yesterday dropped a big hint that she is having a daughter.

As a woman gave her a teddy bear, Kate, 31, said: “Thank you, I will take that for my d… for my baby.”

After the slip on a visit to Grimsby, Lincs, Kate insisted she did not know the sex of her baby — who will be third in line to the throne — with Prince William.

Sandra Cook, who was standing next to a woman who gave Kate the white bear, said: “As she handed it over I distinctly heard Kate say, ‘Thank you, I will take that for my d… ’

“Then she stopped and corrected herself to say, ‘… for my baby’.

“When she shook hands with me I said, ‘You nearly slipped up there, you were going to say daughter, weren’t you?’ She smiled and said, ‘What do you mean? We don’t know yet’.

“I teased her and said, ‘Oh I think you do’ — to which, still smiling, she replied, ‘We’re not telling.’”

Mum-of-two Sandra, 67, had waited for two hours in freezing fog to see Kate make a solo visit to Grimsby, while Prince William, 30, was busy with RAF duties.

She added: “It was worth every cold minute. This lady giving her a teddy seemed to take her by surprise. Everyone else was giving flowers.

“I’m certain it’s a girl. She wouldn’t have said the D-word otherwise. After she said it, she was a little flustered.”
