London, Mar 19: Prince William's wife Kate revealed she is due to give birth to her second child by the "mid-to- end of April," on a visit to a children's centre on Wednesday, March 18.
She let the information slip while chatting to a volunteer at the centre in southeast London, run by a charity working with young families.
"I told her she is beautiful and that she's got a tiny little bump. I asked when her baby is due and she said mid-to-end of April," volunteer Christine Osborne told reporters after speaking to her.
Contacted by AFP, Kensington Palace, the British royal couple's official residence in central London, declined to comment on the report.
Kate is already mother to 18-month-old Prince George, the third in line to the throne. Royal officials announced she was pregnant with her second child in September.
The £35 (48 euro, USD 52) black polka dot maternity dress she wore during her visit toady, from online retailer Asos, sold out within 30 minutes of her public appearance.
