The trio revisited their meeting at Wembley during Taylor Swift's London Eras Tour, when Travis appeared as a backup dancer and later posed for a now-viral selfie with William and the children. The special episode coincided with the rumored date of Travis and Taylor's wedding; William previously gave a "no comment" when asked about attending, and PEOPLE reports the couple are not expected to be guests. William also first met Swift at a 2013 Centrepoint gala, a detail fans recalled during the chat.
