A month shortly after Prince William and Kate Middleton returned from their official visit to Canada, the Duchess is said to be four months pregnant and is expecting a baby girl according to some sources.

Just a week and a half ago, a tabloid announced Middleton was "four months pregnant." The cover story even said she was expecting a girl, and that she planned to name the baby after Prince William's late mother, Princess Diana. "It's official," blared the issue's cover.

Moreover, Life & Style has exclusively learned that the duchess is pregnant with their third child, and that sister Pippa Middleton is planning her upcoming nuptials around the birth.

"Pippa desperately wants the focus to be on her rather than her sister's bump," a source shares of the 33-year-old, who recently got engaged to hedge fund manager James Matthews.

"She may put off the wedding until Kate has had her baby," a friend adds. "Pippa is planning things around Kate."

If Kate Middleton is pregnant and decides to attend her sister's wedding, it might lead to conflict within the duchess' family, according to one report.
"Kate would upstage her sister [if she were maid of honor]. It's a tricky situation for Pippa," Royals author Judy Wade spoke of this issue further with the Daily Mail. "She would want her sister by her side, as who else would she trust to make things go well? ... But if your sister is a future queen, she is going to upstage the bride and draw attention."

Moreover, according to royal author Judy Wade, it's natural that all eyes would be on the future Queen, taking some of the attention away from the bride.

However, Gossip Cop already reported that Kate Middleton is not four months pregnant and while she very may well have another child some day, people will need to wait for the official announcement from the palace.
