Princess Eugenie sparked yet another pregnancy rumor after posting a Mother's Day greeting for her mom, Sarah Ferguson. The York princess shared a series of photos from her childhood with Fergie at the center of it.

The royal wrote in the caption that she wants to celebrate "all the amazing mothers out there" in this most challenging Mother's Day with the pandemic crisis ruining social gatherings. Princess Eugenie said that she's especially honoring moms who cannot be with their kids because they are in the frontlines saving lives or distancing themselves to contain the spread of the virus.

According to Daily Express, the fact that Princess Eugenie greeted "all the amazing mothers" could be a reference to herself as well, if she is expecting her first child with husband Jack Brooksbank. Daily Express stated that bookmakers put the odds of Princess Eugenie announcing her pregnancy this year at 1 to 4 after her Mother's Day post.

Alex Apati of Ladbrokes spoke to the news outlet and said that the likelihood of Princess Eugenie having a royal baby soon is increasing. The bookmaker boldly predicted that it will be the York royal who will give birth next.

Royal fans have been eager for Princess Eugenie to have her first child since marrying in October 2018. The 10th in line to the British throne has been has been with Jack, then the manager of the Mayfair club, since 2010 after mutual friends introduced them.

Friends said in an interview with Entertainment Tonight that Princess Eugenie and Jack are perfectly suited for each other. While Jack didn't finish college, he was a hard worker who climbed the corporate ladder and Princess Eugenie didn't mind that he started out as a waiter.

During the first years of their relationship, Princess Eugenie and Jack spent time apart because of her work and they used to Skype to connect. But by 2015, Princess Eugenie moved back to London permanently and that's when they truly enjoyed each other's company by dining out, traveling and even spending time with her sister Princess Beatrice, and cousin Prince Harry.

Despite being married for nearly two years, Princess Eugenie and Jack haven't made public their plans to expand their family. The York princess, while more outgoing than her older sister, is keen on keeping her private life low key.

Royal fans, however, speculate that Princess Eugenie may be holding off announcing her pregnancy because of her dearest sister. Princess Beatrice is set to marry on May 29 but sources disclosed she could push this back to 2021 because of the pandemic.
