Prince Harry's ex-girlfriend rumored to have appeared in one of Princess Eugenie's wedding photos

What’s that about “three’s a crowd?” Princess Eugenie and Jack Brooksbank were joined by a third wheel in one of their photos, but the newlyweds didn’t seem to mind.

Kensington Palace released four official photos following Eugenie and Jack’s royal nuptials. Dailymail reports that fans singled out one of the shots that showed a beaming Eugenie hand-in-hand with her handsome husband.

Behind them was a woman who appeared to be snapping selfies, oblivious to her photobombing. Eugenie and Jack didn’t seem aware either as they made their way to a private dinner at Royal Lodge Windsor.

Sharp-sighted royal fans quickly pointed out that the blonde woman is Cressida Bonas, a close friend of the bride and Prince Harry’s former girlfriend. It is believed that Eugenie introduced Bonas to Prince Harry, who dated the royal between 2012 and 2014.

Bonas, who is also an actress, was pictured earlier at the royal wedding as she arrived in a stunning blue and black Tory Burch dress with a matching headband and burgundy court shoes. In the photobombed image, she seemed to have changed her clothes for the couple’s more festive evening party.

Harry’s first girlfriend, Chelsea Davy and rumored Ex, Ellie Goulding, were also present to see Eugenie and Jack become man and wife.

The newlyweds chose Alex Bramall, who had previously photographed Eugenie for Harper's Bazaar, to be their official wedding photographer.

The official portraits include one of Jack and Eugenie with their families and the bridal party in the White Drawing Room inside Windsor Castle.

Another showed the couple with their bridesmaids and pageboys only. A third photo, in monochrome, captured Eugenie and Jack kissing inside their Scottish State Coach on their way to Windsor Castle.

Eugenie and Jack tied the knot on October 12 at the St George's Chapel in Windsor Castle, the same place Prince Harry and Meghan Markle got married five months ago.

The royal family and celebrity guests like Naomi Campbell, Robbie Williams, Kate Moss, and Demi Moore were present to celebrate the joyous occasion with Eugenie and her groom.

Prince George, Princess Charlotte, Robbie Williams' six-year-old daughter Theodora, and Eugenie's goddaughter, Maud Windsor, were among the adorable bridesmaids and pageboys that trooped behind the glowing bride.
