Is Kate Middleton pregnant? The Duchess of Cambridge gave birth to her second child, Princess Charlotte last May, and while the 33-year old is showing no signs of slowing down during recent official engagements, a new report claims that she is expecting again and that the Duchess is reportedly carrying twins.

According to OK! Magazine (via Hollywoodlife), a source claims that Middleton and Prince William will soon be parents to twin babies.

"To say she was shocked would be an understatement," a source told the magazine. "She's suffering more from exhaustion than anything else."

While many are pointing out that the Duchess' slim physique appears to say otherwise, the source claims that the royal is allegedly three months along. The insider said that the Duchess "hasn't had much of an appetite, so she's hardly gained any weight."

And while the Duchess is said to be bearing the discomfort that comes with pregnancy, the source said that everyone wants to make sure that she is taking care of herself. The rest of the family is reportedly "so excited" at the prospect of twins. As for the Duchess, she is said to be "discouraged" at the thought of having to care for four babies under the age of three, and the thought of many months of sleepless nights taking care of twin babies is allegedly causing her to panic.

Though the report has yet to be confirmed or denied by an official statement from the palace, the Duchess'a back-to-back official engagements appear to debunk the pregnancy speculations. During the first few months of her first and second pregnancies, the Duchess suffered from severe morning sickness, or hyperemesis gravidarum, which required her to take a bed rest. Seeing the mother of two out and about and looking at the pink of health at the state dinner honoring Chinese president Xi Jingping and also looking red-carpet ready at the premiere of "Spectre" last month appear to prove that she is not pregnant.

Meanwhile, Gossip Cop reports that OK! magazine's claim is false, and the website says that a palace insider told the website that the story is categorically "untrue."
