Is it time for Kate Middleton to have another baby? Her youngest child with Prince William is turning two years old, and a royal expert believes she will be the first to get pregnant in 2020 than Meghan Markle or Princess Eugenie.

Royal expert Angela Mollard said in a podcast that Kate will be pregnant with her fourth baby early this year despite betting odds favoring Princess Eugenie. Mollard is also certain that the Duchess of Cambridge wants the four children.

Ladbrokes revealed that the popular odds of Kate getting pregnant in 2020 are 3/1, while Princess Eugenie's odds were at 1/2. Royal followers don't think Meghan Markle will rush to have another baby in 2020 as the betting odds were at 6/4.

However, Mollard also said that Princess Beatrice could be the wildcard. The York princess, who is engaged to Edoardo Mapelli Mozzi, might just ditch the wedding altogether in light of her father, Prince Andrew's controversy. The royal expert suggested that Princess Beatrice should start with a family and sort out her wedding plans later on. She is, after all, already standing in like a parent for Mozzi's son from a previous relationship.

Meanwhile, royal fans speculate that Kate might be already pregnant this time. Apparently, the pregnancy rumors resurfaced when the Duchess of Cambridge skipped one event with Prince William in late November. She was not also with her husband when Prince William flew to Kuwait and Oman early this December.

While Buckingham Palace has not made any announcement, Kate's absences at some of the royal events have fans wondering if she's having morning sickness again. In all three of her pregnancies, the duchess suffered from extreme morning sickness so she had to take a leave from her royal duties.

But Kate was ever-present at the Queen's diplomatic reception on Dec. 11. She came to the affair wearing her mother-in-law, Princess Diana's Lover's Knot tiara.

Princess Diana received the headpiece as a gift from Queen Elizabeth when she married Prince Charles in 1984. According to The Sun, it's one of Kate's favorite pieces, which she also wore for a royal event in 2016.

Prince William's wife also wore a red and blue sash and a pin of the Dame Grand Cross of the Royal Victorian Order for this special evening. There were gifts of the highest honors from Queen Elizabeth last April when Kate and Prince William celebrated their 8th wedding anniversary.
