Kate Middleton is once again surrounded with rumors of her pregnancy. A new report says that the Duchess of Cambridge is expecting twin girls.

According to OK! magazine, Middleton found out about the news after undergoing a sonogram.

“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 oven,” Hollywood Life reported, citing an OK! magazine source. The report added that Middleton and her husband Prince William were not planning to have a third baby.

The report also said that Middleton sent the sonogram picture to William, who was surprised by the news.

“He immediately called her and said, ‘You’re joking aren’t you? We’re not really having another baby right now,'” the source said, adding that the 34-year-old told the Duke of Cambridge that she was 12 weeks pregnant.

However, Gossip Cop debunked the report about Middleton’s pregnancy calling it "false."

This is not the first time OK! magazine has said that Middleton was having twins. In October 2015, the outlet reported that the duchess was a “little discouraged” with the news of her third pregnancy.

Since Middleton gave birth to Princess Charlotte in May 2015, several reports have said that the duchess was planning another baby.

Last month Life & Style magazine reported that the royal couple made the announcement of a third child to their family on Christmas 2015. However, all reports turned out to be just rumors.
