Kate Middleton Pregnant? Sources Say 'Yes'

No need to worry, Katie Couric, Kate Middleton might have good reason to put on some extra pounds.

Could it be that Prince William and the Duchess of Cambridge will soon be having their first child? 

"Friends say Kate is convinced it's happened, and while she and William are keeping the news close to the vest, they're delirious with joy," an insider confirmed to Star magazine (via Hollywood Life). "A woman can always tell when the earliest signs appear, and it's believe that a passionate night together at their rented country house on an estate in Wales, just after the end of the London Olympics, did the trick."

During the Olympics, body language expert Linda Talley told Hollywood Life:  "William sits in a very open position. Both she and her Prince have genuine smiles as they gaze at each other. Even after a year, it appears the honeymoon is still on."

But an official announcement could be held back for as long as two months, Star magazine reported. "It would be formally through the palace press office, but only after the royal gynecologist is absolutely convinced that Kate is in peak condition," the source said

Middleton allegedly wants a daughter and would like to name her Diana, in honor of William's late mother, but that "may shock the Queen" considering their rocky relationship toward the end.

During the Jubilee interview with Couric, William said, him and Middleton were eager to have kids.

"More importantly, I'd rather like to have children," he said. "So that's the key thing really. But I'm just very keen to have a family and both Catherine and I..are looking forward to having a family in the future."
