Reports that Duchess of Cambridge Kate Middleton is pregnant with their third child have been swirling around.

There is speculation in the media that Prince William’s wife is four months pregnant and is due on Christmas. A source of a well known publication said: “Kate and [Prince] William are overjoyed.” Queen Elizabeth II reportedly is also delighted with the news and said it is a fabulous present for her 90th birthday.

Middleton and William want at least four children. The royal couple apparently don’t mind whether their third child is a boy or a girl as long as the baby is healthy. The news is reported by Life&Style magazine.

Kensington Palace has not made any official announcement with regards to Kate Middleton’s pregnancy. The couple is already parents to Prince George, who is about to turn 3 this month, and Princess Charlotte, 14 months.

In April, Middleton opened up about her life with Her Majesty The Queen on the ITV documentary Our Queen at 90.

The Duchess of Cambridge revealed that she takes lessons from the Queen about managing her own two children. Middleton said the Queen was very pleased with the birth of Princess Charlotte. She disclosed that Queen Elizabeth is very fond of Charlotte and takes an interest in what she is up to.

Prince William’s wife has also made headlines over her rumored health problems. Now that there have been news of Kate Middleton’s pregnancy, many are waiting for what she will wear when the baby bump starts to become obvious.

The royal family has been consistently slammed for their lifestyle. Since Middleton became part of the family, all eyes have been focused on her style, even during when she was pregnant with George and Charlotte. There have been rumors that she is becoming more brand conscious in terms of dressing up. Just recently, Kate Middleton wore a £2,300 ($3,000) dress made by Alexander McQueen for an event.
