Kate Middleton has got rumour mills spinning again with brand new speculations about her third pregnancy. According to the latest buzz, the Duchess of Cambridge is expecting her third baby with Prince William and the royal couple is keeping the news under wraps.

If the new reports are anything to go by, then Kate's tired and pale look at royal engagements and her attempt to hide a baby bump is a clear indication that the mother of two could be carrying her third baby now.

Kate Middleton's daughter Princess Charlotte is about seven months old and the Duchess has just returned from her maternity break. But several reports have pointed out that Prince William's wife has been spotted at various royal engagements looking pale and tired.

Kate Middleton, who is known for looking glamorous at all her public appearances, has been looking washed out in a series of events, including a charity appearance and a holiday shopping trip in Chelsea, reported Radar Online.

The report said that the Duchess wore a houndstooth coat that covered her midsection and during the event she "pulled her newly lobbed hair haphazardly into a clip".

A couple of weeks ago, when Kate Middleton attended the Place2Be Headteacher conference in England, Inquisitr pointed out that the Duchess was photographed covering her stomach with her clutch throughout the event. In fact, she was reportedly doing the same at an evening soiree in a Saloni, a day before this event. The report further stated that in a series of photographs, the eldest Middleton daughter is seen wearing a turquoise and grey dress and holding a black clutch close to her belly.

Kate Middleton pregnancy rumours have been running wild for the last couple of months with reports suggesting that Kate and Prince William have been contemplating to expand their family and that the Duchess is already in her early stages of pregnancy as she is suffering from major sickness. In fact, some reports have also claimed that the royal couple is indeed going to be parents to twins and will soon be making an official announcement.

Going by the trend, none of these stories have turned out to be true, now only time or a royal announcement by Kate Middleton and Prince William will confirm if there's any truth in this latest pregnancy rumour.
