The 23-year-old, who looked elegant in a Reem Acra gown, performed at the gala, along with Bon Jovi. At one point, the famous singers even got together to belt out the band’s hit “Livin’ on a Prayer” — and William joined in!
A shaky Instagram video captured the moment, and Taylor shared her own photo of the threesome singing along. Her night in the palace comes just two days after she won big at the American Music Awards, even taking home the coveted Artist of the Year award for the third year in a row.
