The carousel of images included a close up of the engagement ring, which features an elongated cushion cut diamond set in an antique gold band.
Reports suggest the sparkling stone is valued at between £500,000 and £750,000 – which comes as no surprise as it was announced earlier this month that Taylor is offically a billionaire.
Since being shared on Swift’s Instagram at 6pm yesterday evening, the post has already attracted more than 26 million likes.
She and Travis posed for a backstage picture with Prince William, Prince George and Princess Charlotte after the family attended one of the London dates on her record breaking Eras Tour.
The moment quickly became one of the standout highlights of the tour’s UK leg, with royal fans and Swifties alike delighted by the crossover.
Taylor later uploaded the snap to social media with the caption: “Happy Bday M8! London shows are off to a splendid start.”
The post went viral within minutes, with thousands of comments from fans praising the unexpected meeting between pop royalty and the royal family.
