Rumor mills are abuzz with Kate Middleton's pregnancy news.

Multiple media reports claim that the Duchess of Cambridge and Prince William are expecting their second baby together. It is also said that that she is around three months along.

The royal couple welcomed their first child, Prince George Alexander Louis, just six months ago. However, rumors of Kate being pregnant are doing rounds after Star Magazine reported that it was official that the 31-year-old is pregnant for the second time.

"It's official Kate's pregnant again," the magazine's cover page screamed out loud. It further reported that William shared the happy news with family during Christmas at their palace. "Kate, who turns 32 on Jan. 9, and William, 31, indeed are now expecting their second child," the magazine said. "The royal family is overjoyed with the stunning turns of events."

Furthermore, the second pregnancy news seemed to be a delightful one for granny Carole Elizabeth Middleton. The mag reported that she even decided the name of her second grandchild. "If it's a girl, they'll name her Diana, after Prince William's mother," Star reported.

The reports say that Kate was seen flaunting her tiny baby bump during an outing in London.

"Kate only recently confirmed it with her doctor, and then shared the happy news with William," a source told the magazine.

"Kate and William will, of course, be happy with a healthy baby of either sex, but Kate is really hoping for a girl this time. She feels a little sister for George would be perfect," an insider told the magazine.

However, the news has not been confirmed by the Palace officials yet.
