The “Birthday” singer shared a photo of their pair, showing off their best “duck faces,” while hanging out at the London arena. “…And on the 2nd LDN show the Queen graced me with her presence,” she wrote.
Meanwhile, Adele had equally nice things to say back to her fellow chart-topper. “Katy Perry was supreme tonight!” she tweeted after the show.
Earlier this month, the “Skyfall” singer pumped up her fans by alluding that she’ll release a new album before the year is up. This will be her first studio album since 21 in 2011.
