Rihanna is known as a woman with many surprises. She had another one up her sleeve as she showed up to surprise the crowd at a Paul McCartney show to perform their hit “FourFiveSeconds”.

Paul was performing at week 2 of the Desert Trip Festival just outside of Los Angeles. When the song came on, Rihanna came out and performed it with him. He performed it last week as well but Rihanna wasn’t there.
