Kate Middleton reveals her due date (+ latest photos!)

Here she is again! The Duchess of Cambridge , née Kate Middleton, made yet another appearance today. She paid a visit to the Brookhill Children's Centre in in Woolwich, East London.

To this event, Kate wore a black-and-white polka-dot maternity dress by ASOS, which is making news today because it's a mere $63; so, it's been flying off the—yes, now empty—shelves. The dress sold out just an hour after Kate was seen wearing it! (ASOS says it'll be back in stock next week.)

But the dress is not all everyone's talking about! Not at all. The bigger news is that the Duchess revealed the royal baby's due date.

We can thank Christine Osborne, one of the charity's volunteers, for flat-out asking Kate when the baby's due to arrive.

"I'm due mid-April to the end of April," Kate responded. "Not long to go now."

The visit to the Children's Centre began with a coffee meet-and-greet. Next, Kate observed a training session for the volunteers and finished the day at the Together for Twos' daycare.

Kate was also given gifts to bring home to 19-month-old Prince George—including, according to Hello! Canada,  an Elmer the Patchwork Elephant book, a potty training book, a colour-sorting clock and a manual on how to teach children to tie their shoelaces.

"Oh that's perfect," laughed Kate, pointing at the potty training book. "We will certainly be needing that!"
