Royal couple Kate Middleton and Prince William are once again in the middle of another pregnancy rumor. And this time, reports claimed that the Duke and Duchess of Cambridge are expecting twin girls.

Ever since Duchess Kate welcomed Princess Charlotte over the summer, there have been incessant reports that the 34-year-old mom-of-two is pregnant with her third child. And just recently, reports circulated that Will and Kate are not just expecting one baby but twins.

"It's early days, but the buzz in the royals' inner circle is that Kate's pregnant again, and this time she's got not one but two buns in the over," an OK! magazine (via Hollywood Life) insider said. "They weren't even trying."

The source further claimed that the Duchess informed her 33-year-old husband by sending him a picture of a sonogram. The source also added that Duchess Kate reportedly explained that they're expecting twins and she was 12 weeks along.

"He immediately called her and said, 'You're joking aren't you? We're not really having another baby right now,'" the royal insider said, adding that Prince William is planning to name one of the twin girls Diana.

Aside from the pregnancy speculations, which apparently Buckingham Palace has confirmed, the royal couple are also reportedly looking for a new place to live. According to Inquisitr, Duchess Kate and Prince William will be moving out of the Kensington Palace with no nannies or hired help. Anmer Hall, however, will be the Cambridges' permanent home.

The latest royal pregnancy report also revealed that the Duchess is not experiencing any morning sickness as she did while pregnant with Prince George and Princess Charlotte. Thus, The Hollywood Gossip debunked Ok! magazine's report, saying "this story is crap."

"She's not pregnant," the celebrity gossip site wrote. "No one moving out of Kensington Palace, nor is the staff going anywhere. The end."

This has not been the first time that the royal couple have been reported to be expecting a baby. But a Life & Style report in January cited an unnamed source that Will and Kate didn't think they'll have a third baby soon.

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

Meanwhile, Kate Middleton's recent pregnancy rumor came after the royal couple were spotted enjoying a low-ley pre-Valentine's date at The Crown Inn at East Rudham. As reported by Vanity Fair, the royal couple descended into the world of the normal and dined on "pan-roasted Halibut steak and wild mushroom risotto."

The publication further noted that Prince William enjoyed his glass of wine, while Duchess Kate opted to drink sparkling water. So, does it the sparkling water mean the Duchess is indeed pregnant?

It is often difficult to find the truth in Kate Middleton's pregnancy reports since most of them turned out to be false. Duchess Kate has also been spotted making public appearances in the past few weeks with no signs of a pregnancy.
