Princess Kate and Prince William once made a secret trip to watch Rihanna and Kesha, as confirmed by Scott Mills.
The British DJ has disclosed the fact that the Prince and Princess of Wales made an undercover trip to Radio 1's Big Weekend in 2010.
Kate and William attended the festival, held in Bangor, North Wales that year, to watch Rihanna, Paramore, and Kesha perform.
Speaking to Heat magazine, Scott said: "I remember them turning up to Radio 1's Big Weekend years ago in Bagor, North Wales.

"The bosses knew, but the rest of us had no idea for obvious security reasons.
"It was kept quiet, but they were watching Rihanna at the side of the stage. I like it that they got involved."
Mills has interviewed William and Kate in the past, with the couple making an appearance on his Radio 1 show in 2017 to speak about mental health.
The presenter also revealed William was an avid Radio 1 listener at the time, although he has since made the switch to Radio 2.

"He used to text in all the time - obviously not going, 'Love HRH' - but he would text in and chip in with the conversation via Radio 1's normal contact number," Mills said.
The Waleses are known to love attending concerts, as Prince William took his eldest two children, Prince George and Princess Charlotte, to watch Taylor Swift's Eras Tour.
When George, 12, and Charlotte, 10, attended the concert, Swift published a photograph from backstage with the Waleses alongside her boyfriend, Travis Kelce.
The singer-songwriter captioned the post: "Happy Bday M8! London shows are off to a splendid start."
