Kate Middleton's new diet has sparked pregnancy rumors.

The Duchess of Cambridge was reported to be nearing the end of her first trimester as of February. It was initially said that she was expecting a girl, but now reports say that she may be expecting twins, according to International Business Times.

"She'd been trying to eat yams after someone told her they help you have twins-the peelings are thought to contain a chemical that causes hyperovulation. And she's drinking lots of milk, eatings lots of cheese and has a tub of Greek yogurt every day," a source told OK! magazine.

The source also added that Prince William would love to have at least two daughters.

"With all the boys in his family, he's trying to even up the balance," the source said.

The alleged pregnancy was a great way to start off the year, and both Prince William and the Duchess are overjoyed, according to the magazine.

"William was ecstatic! He couldn't stop hugging her," the source said. "He was actually a little surprised, because he was convinced it would be a boy. In his head, he was expecting a brother for George, because he himself grew up with a little brother..He knows his mother, Princess Diana, would have been overjoyed."

The couple could use happy news—they are being accused of abandoning Prince George.

They went to the Maldives for vacation without their son. It's being called the couple's second honeymoon.

Prince William and Middleton will be touring New Zealand and Australia for three weeks with their son next month, and she recently vacationed with their son. Still, people are calling out the royal pair for leaving their 8-month-old son with Middleton's parents.

"I like them but am shocked by this, just makes me think they are the same old royals ... Can't imagine choosing to be so far from my baby for so long," said a Twitter user, according to The Hollywood Gossip.
