Michelle Williams and Destiny’s Child joined the megastar on stage at the US music festival – which aired early in the morning in the UK.
Twitter went into meltdown when the two stars joined the headline act for part of her long-awaited set.
#Beychella has been trending on Twitter ever since, with fans rushing to praise the wide-ranging setlist, which also roped in Beyonce’s sister Solange.

Twitter understandably went into meltdown when the women appeared together, with one person joking: “Destiny’s child did more for America than the founding fathers.”
“GOD BLESS COACHELLA FOR GIVING BEYONCÉ A LONGER SET THAN THE SUPER BOWL DID SO WE COULD FINALLY GET THE DESTINY’S CHILD REUNION MEDLEY WE DESERVE. #Beychella,” said another.
A third beamed: “The Queen is back. Destiny’s Child reunited. Beychella 2018. History has been made.”
“Natural vocals on PITCH every time! Choreo delivered & performed EFFORTLESSLY! 3 outfit CHANGES! Destiny’s Child REUNION! Sibling dance off! FEMALE EMPOWERMENT! Speechless!” enthused a fourth.
Beyonce will now prepare to head off on tour around the world with husband Jay Z.
The On The Run II jaunt includes a handful of dates in the UK and many other territories worldwide.
She is also expected to release a new album later this year, if rumours are to be believed.
