Rumors are rife that the Duchess of Cambridge Kate Middleton is pregnant again. The royal is understood to have gained a lot of weight, which has added fuel to fire.

Additionally, a new revelation has come from Kate's sister Pippa Middleton, in regards to this rumor. 

Pippa who recently appeared at the Matt Lauer show may have hinted that Kate is expecting a second baby. Pippa was reportedly telling a few people behind the sets of the show that Kate is pregnant and Prince George will soon be getting a new sibling, according to Celebdirty Laundry

Moreover, reports also suggest that Kate's pregnancy is in its early stages. The duchess' physical appearance has also become a matter of speculation and it is being said that she has become bloated and looks tired. Her looks sparked speculation when she recently appeared at a public event.

It is also being said that Kate and Prince William would make the big announcement on Prince George's birthday, as they think that a sibling would be the best gift to the toddler. It is also said that the reason for them to have a second pregnancy so soon is that they want to have another child close to Prince George's age.

Previously, it was rumored that Kate is going to have a baby girl.

"Kate has already told William, 'I'm having a girl!'" a source told the Globe Magazine last month, according to Cosmopolitan. "She's only 14 weeks along. [But] she told William she feels so much different than her first pregnancy, when she had to be hospitalized with severe morning sickness that plagued her for weeks."

Though the royal family has not confirmed the reports of the pregnancy, it was earlier rumoured that the royal couple has also thought of a name of their soon to be born daughter.

"William has always said that if he had a daughter, he'd like to name her after his late mother, Princess Diana. Queen Elizabeth has given her blessing. ... She knows how much it would mean to William to honor his mom," the insider had told the magazine at that time.

Meanwhile, it is being said that Kate and Prince William are going to keep Kensington Palace as their official home.

"Kensington Palace will be the Duke and Duchess's home for many years to come, including when he becomes Prince of Wales. I don't think we know for sure what will happen to Clarence House but I think we've always said Buckingham Palace will remain the monarch's residence," a source told Express
