Her sister may have had a regal, official wedding, but Princess Beatrice just attended one of the coolest celebrity nuptials of 2019!
The ninth in line to the British throne jetted over to the US to celebrate supermodel Karlie Kloss and her husband Joshua Kushner's Western-themed second wedding - and she looked like she had a blast.
In a series of photos shared to Karlie's Instagram stories, Princess Beatrice can be seen amongst the guests, dressed in a casual denim shirt, standing next to fellow Brit and known friend of the royals, Ellie Goulding.
Duchess Meghan's close friend Misha Nonoo and her fiancé Mikey Hess were also snapped in the same shot, the latter of whom can be seen singing animatedly into a microphone.
The eldest daughter of Prince Andrew and Sarah Ferguson was also seen in a shot of the long dining table chatting to another guest who is not visible in the frame.
Could it have been her boyfriend and potential plus one Edoardo Mapelli Mozzi?
The former Victoria's Secret model and Princess Beatrice have been friends for years and this isn't the first time Bea has appeared on Karlie's Instagram.
The two attended a wedding as each other's dates back in 2016 and just last year, went on a trip to Jordan along with Misha Nonoo, Mikey Hess, Ellie Goulding and Karlie's husband, Joshua Kushner.
Following her engagement to her now husband in July 2018, Karlie shared screenshots of her friends reacting to the engagement news and we think we loved Princess Beatrice's shocked reaction the most! Plus, we learned of the Princess' secret Instagram account that sadly for us, is set to private.
Karlie and Joshua's second wedding may have had a fairly casual dress code, but the guest list was packed full of A-listers.
Along with Beatrice, Ellie and Misha, guests included Katy Perry and Orlando Bloom, fashion designer Diane von Furstenberg, Mila Kunis and Ashton Kutcher as well as Crown Prince Hussein of Jordan and his sister Princess Salma.
