Princesses Beatrice and Eugenie might be British royalty, but that doesn't mean they can't let their hair down once in a while.
And the two sisters did exactly that during a fun concert held in London over the weekend, where the two were pictured having a good old boogie to one of pop music's most legendary icons.
Attending the British Summer Time concert in Hyde Park, Beatrice and Eugenie were all smiles as they danced the night away.
And while the pair would undoubtedly have had fun together at any concert, the night was made even better when none other than Celine Dion stepped out on stage to perform some of her biggest hits.
The royal sisters were clearly loving it as pictures from the night show the pair having a grand old time (and a good old fashioned boogie!)
The two sisters were looking stylish for the occasion - Beatrice wore an Alexander McQueen dress which featured a chic print, while Princess Eugenie wore an Aztec-inspired printed dress.
Following Celine's whirlwind performance, the popstar shared a stunning image to her Instagram accompanied by the caption: "London, we had an amazing time last night! Thank you for all the love."
She finished by adding: "Can't wait to see you again soon!"
It's also understood Beatrice's boyfriend, Edoardo Mapelli Mozzi was also in attendance at the event.
The pair, who only this year made their first public appearance together, look to be spending a lot of time together.
First stepping out at the Portrait Gala together in March, the pair looked to be completely smitten.
It was an important outing for the pair and showed that things were certainly getting serious for them.
In May, Mozzi also accompanied Beatrice and her mum Sarah Ferguson to Lady Gabriella Windsor's wedding.
This was yet another sign that things were getting serious between the pair.
Here's hoping the pair have plenty more fun nights out at concerts between formal royal events to come!
