Princess Eugenie’s upcoming wedding to Jack Brooksbank is expected to feature celebrity guests like Robbie Williams, David and Victoria Beckham, and Elton John. And one big name who will likely attend is the bride's close friend Cressida Bonas—who just so happens to have dated Prince Harry.

Eugenie and Cressida have been close friends for many years, and have been pictured attending many high-society events together since at least 2013.

Eugenie reportedly introduced her cousin Harry to Cressida in 2012, but the two broke up two years later so Cressida could focus on her career, BBC reports. Cressida is an actress, and most recently performed in the play The Dog Beneath the Skin, in which she played a dog jealous of its owner’s fiancée.

Cressida usually refuses to speak about her past relationship to the press, and instead prefers to keep the attention on her acting work. These days, she is dating another Harry—Harry Wentworth-Stanley. The two have posted photos of their travels together.

This Harry has a royal connection, too. Back in June, he met with Prince William as he opened James’ Place, 'a non-clinical centre for men experiencing suicidal crisis,' according to its official website. The centre is named in memory of Harry’s older brother, James, who died by suicide at the age of 21.

Eugenie also posted about the charity and William’s appearance at the opening, praising Harry and James’ mother, Clare.

Given the couple’s royal connections, the run-in with the Duke and Duchess of Sussex is unlikely to spark any awkwardness. In fact, Cressida was a guest at Meghan and Harry’s wedding back in May. She even wrote about the experience afterward—though only about the stress that came with having to choose a hat.
