In the last quarter of 2015, rumors have emerged that Kate Middleton is expecting her third child with husband Prince William. And the hearsay started once again that the Duchess of Cambridge has a baby on the way.

On the Jan. 6 article of Life & Style, they first reported that the 34-year-old Princess and the Duke of Cambridge announced that they are expecting to their families on Christmas day. In fact, her brother-in-law, Prince Harry, can't contain his happiness as he jumped and cheered around with excitement.

It has been already said that Kate is actually two months pregnant and very happy. In fact, it even surprised the Royal couple themselves with the new addition, but it has been known that they are very vocal that they wanted to have a big family.

"Kate and William have always wanted to have a large family," a source of the publication said. "But they didn't think they would be expecting baby No. 3 quite so soon."

On the contrary, Reveal added that the Kensington Palace hasn't announced any baby news aside from Prince George's first day in school. To recall, the 2-year-old only son of Kate and William caught everyone's attention when his photo had surfaced online.

Also, an insider from the palace asserted that the mother-of-two is not really pregnant and the rumors are not true. Meanwhile, Kate just recently celebrated her birthday on Jan. 9 in a private get together at Amner Hall.

As simple as she is, the Princess opted to have a "low-key" celebration with her family and some close friends, according to International Design Times. She enjoyed her special day with William and her two kids with the rest of the Middletons.

Later, on Sunday, Kate together with her parents, Carole and Michael, brother and sister, Pippa and James, attended a morning mass at Sandringham on Sunday. Of course, Prince William accompanied them to mark the 100th anniversary of the Gallipoli campaign during World War I.
