Kate Middleton is reportedly pregnant again. Almost a year after the birth of her first child Prince George, the Duchess of Cambridge is preparing to welcome second royal baby with Prince William.

Citing the claims of New Idea magazine, Radar Online reports that Kate Middleton's pregnancy news has been confirmed by the Duchess' "long time friend," Jessica Hay, in an exclusive interview with the magazine. According to the report, the royal couple is expected to make the official announcement in the "next few months."

"Kate's inner circle are buzzing with the news that she is pregnant" Jessica Hay told the Australian magazine.

"I've heard it from several different friends of theirs now and they're saying that they think there's going to be an official announcement in weeks," Hay added.

The Web site notes in the report, that Jessica Hay is the same friend who "famously confirmed" Kate Middleton's first pregnancy back in Nov. 2012. The news was spilled just few days before the official confirmation from the British royal family.

Kate Middleton has been slammed with pregnancy rumours for quite some time, which remained unconfirmed. However, this time the Duchess of Cambridge is reportedly showing the early signs of pregnancy. The report notes that Kate Middleton has begun to gain pregnancy weight. The friend says that Kate Middleton's face has become "fuller like it was when she was first expecting George."

Noting the change in Kate Middleton's hairstyle, the friend suggests that the change could be "to disguise the fullness" of her face.

"She has rosy cheeks, she's letting her greys show again, and whenever she's out in public she goes to great lengths to hold something over her tummy..." Jessica Hay tells the magazine.

Meanwhile, the friend suggests that the royals will try to keep Kate Middleton's pregnancy news under the wraps "for as long as possible." Unlike Prince George's time, the Duchess wants to keep the news from becoming public until 3-month period passes.

The Web site notes that Kate Middleton is also adopting a relaxed royal events schedule.

Earlier this month it was reported that in the August 2014 issue of Vanity Fair magazine (via Hollywood Life), a palace insider has revealed that Kate Middleton and Prince William "plan to try this summer" for the second child.

This is not the first time reports claiming Kate Middleton is pregnant with her second child have surfaced. The big revelation may have come from believable source, but these reports must be treated as rumours as long as the palace issues a press release confirming Kate Middleton's pregnancy.

In the meantime, a big event for the royal family is approaching. Kate Middleton and Prince William are speculated to be already planning for the celebration of Prince George's first birthday on July 22.
