Kate Middleton pregnancy: Duke of Cambridge and Duchess expecting third baby?

Just days before Pippa Middleton's wedding, rumours of Duchess of Cambridge Kate Middleton's third pregnancy have started doing the rounds. According to reports, Kate is already 15 weeks pregnant.

OK! Magazine now claims that Kate and Prince William are expecting a third child and they both are "ultimately excited." The magazine also said that this baby was a surprise, as they were not even trying.

"That said, they weren't trying, either. It's something they'd never enter into lightly, understanding the risks. But they've grown so much as individuals and as a couple through parenthood," an insider told the magazine.

Kate is reportedly 15 weeks pregnant, but neither the Duchess nor the palace has made any official announcement about the third royal baby because of her sister Pippa's wedding.

"Kate would never want to steal Pippa's thunder. But they can only keep this in the bag for so long," the source added.

However, Kate and William have already told their children – Prince George and Princess Charlotte – about the baby and they are also excited to welcome their sibling. "The kids were thrilled. Charlotte's been asking to have a sister 'like her dolly' for months now, so you can imagine how excited she was. [He] feels like he has this big brother thing down. He likes playing the role of leader," the insider said.

The report also suggests that William and Kate have selected godparents for their third baby and they want Prince Harry and his girlfriend Meghan Markle to take the prestigious roles. "Will reportedly has such faith that Meghan Markle will be Harry's wife, he plans to ask them both to be godparents," the source said.

But this is not the first time that Kate's wild pregnancy speculations have taken the spotlight. In April, there were reports that Kate and Meghan both are expecting babies, but Gossip Cop dismissed the reports at that time.
