Pregnant Kate was overheard saying "not long to go now" at an engagement in mid-March
Kate was carrying out one of her last engagements before she went off on maternity leave in mid-March, when she revealed her rough due date. The pretty Duchess was visiting a children's centre in Woolwich, London, run by charity Home-Start, when she was asked the all-important question.
"I told her she is beautiful and that she's got a tiny little bump," said volunteer Christie Osborne, 49. "I asked when her baby is due and she said mid-to-end of April."
Kate was also overheard saying, "Not long to go now."
