Beyonce is set to headline the UK’s annual Glastonbury Festival tomorrow night in London … and rumors are now swirling that she will be joined by two VERY familiar faces: her former Destiny’s Child band-mates Kelly Rowland and Michelle Williams!

It is being reported by various UK media outlets that Queen B has asked Kelly and Michelle to join her on stage Sunday night (Jun 26) for her headline slot during the her concert at Pyramid Stage at Glastonbury 2011. According to the reports, if the trio decides to re-unite on stage, crowds can expect them to perform a medley of their hits, including “Survivor,” “Bootylicious,” “Independent Women” and more.

Kelly has been tweeting about being in rehearsals for her upcoming BET Awards performance all week … however, she doesn’t say exactly where she’s rehearsing. Keep in mind that Beyonce’s performance at Glastonbury will be streamed live via satellite during the show.

According to the UK’s Daily Mail:

A story in the Daily Mirror claims Michelle first suggested the idea that the girls get together and now it seems all three will at least spend some time together at the festival.

An insider claimed: “Beyoncé was over the moon and sorted them out with Access All Area passes and accommodation. From there, plans developed and the idea of a brief on-stage Sunday evening reunion was mooted. It’s still very much up in the air as no one wants Bey to feel she’s being upstaged. One idea is for the two girls to join her on stage towards the end of her set for a medley of their hits. But whatever happens, the three girls are getting back together at Glasto and planning on having an absolute ball.”

The last time Beyonce, Kelly and Michelle performed as a collective was in 2006 during the NBA All-Star Game where the ladies blew the crowd away with a moving rendition of the U.S. National Anthem,  “The Star Spangled Banner.”

If the ladies do decide to perform together tomorrow … it will be their first live performance together in half a decade! Not to mention all of the press and publicity Beyonce will receive just in time for her album’s release this Tuesday (Jun 28).
