The royal couple were chatting to soldiers after a St Patrick’s Day parade when Guardsman Lee Wheeler asked the five-month pregnant Duchess if she knew the sex of the baby yet.
“She said ‘not yet'”, the Guardsman told the Mirror. “She said ‘I’d like to have a boy and William would like a girl’.”
Guardsman Jason Perry also spoke to the Kate Middleton saying: “I wished her congratulations and said I hoped everything is fine. She said ‘yes it is’.
“I asked her if she was excited to be having her first child. She said ‘very’.”
