Rumors have been buzzing around about the Duke and Duchess of Cambridge saying that the royal couple is expecting another baby, this time a little princess.

People started looking for telltale signs that Kate is pregnant after Jessica Hay, Kate's childhood friend, said on July 14 that Kate was expecting.

In 2012, it was also Hay who revealed that Kate was pregnant with Prince George weeks before it was royally confirmed.

The royal couple has not yet confirmed the news, but people are already speculating after pictures of the Duchess with a growing baby bump circulated the Web.

"Kate's inner circle is buzzing with the news that she is pregnant. 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 said.

Hay said Kate's face is beginning to look fuller like it was when she was first expecting George.

Hay also said that the Duchess has been wearing her hair differently possibly to cover the fullness of her cheeks. Hay added that Kate's cheeks are always flushed and that Duchess always finds something to cover her tummy whenever she's out in the public.

Kate's friend divulged that the royal family may take some time before bringing the news of Kate's pregnancy to the public. Kate is reportedly going to wait until she is three months into her pregnancy before announcing the news.

"With George, they were forced to tell the world very early on that Kate was pregnant because she was rushed to the hospital with that awful hyperemesis gravidarum at around six or seven weeks," Hay revealed.

"She feels different this time around, and is convinced they're having a girl," a royal insider said.

Meanwhile, Prince George, the first born of the Duke and Duchess of Cambridge celebrated his first birthday on July 22.

The royal birthday party was held at Kensington Palace, and George's grandmother Queen Elizabeth II, was in attendance.

Also guests at the Prince's first birthday were Prince Harry, Pippa, James Middleton, and George's cousin, Mia Grace Tindall.
