Princess Eugenie shared candid snaps with her fiancé, Jack Brooksbank, on social media after inviting the public to their royal wedding.

The next royal bride took to Instagram and shared sweet photos with Brooksbank just days after inviting the public to their big day. In the first snap, Princess Eugenie is staring lovingly at her future husband while the latter looks straight at the camera. The second photo featured the couple with their back on the camera with Brooksbank placing a hand on Princess Eugenie's should while she has her hand on his waist.

"Jack and I are excited to be able to invite people to watch our wedding inside the Precinct of Windsor Castle. Find out more via," she wrote in the caption.

Prince Princess Eugenie has noticeably lost weight ahead of her big day. In fact, even experts noticed it and they praised the bride-to-be.

"Princess Eugenie has a gorgeous shape with all the right curves but it does appear more recently she may have shed some body fat in prep for her wedding," said Jess Tonking.

"I believe she may have lost three per cent body fat (four pounds of fat loss) in the 6 weeks since the Royal wedding," the fitness expert continued. "Half a percent a week is a healthy and manageable amount of fat loss which can be maintained. It may not sound like a lot but this is a great achievement, everyone should focus more on fat loss percentage rather than weight."

On the other hand, Daria Kantor, the founder and CEO of TruBe noticed Princess Eugenie's slimmer frame, too. According to her, the royal did it in a healthy way.

"Princess Eugenie seems to have lost weight in a healthy fashion. Her skin is glowing, she looks fitter and more toned – she's clearly put the work in," Kantor explained.

For Princess Eugenie's wedding gown, Richard Fitzwilliams advised that she choose an "ideal" bridal gown. The royal commentator is not impressed with the next royal bride's fashion.

"There are members of the royal family who are style icons but this could not be said of Eugenie who has not distinguished herself in the sartorial stakes so far," Fitzwilliams told Express. "I think she will choose a delightful wedding dress and the wedding itself will be charming… Memories of Beatrice and Eugenie's outfits at William and Kate's wedding do die hard, so Eugenie must make sure she chooses the ideal wedding dress on her big day."
