Michael Jackson tribute concert
Beyoncé will perform the Michael Jackson tribute concert in October...via a satellite link-up.
The 'Michael Forever Tribute' event takes place on October 8 at Cardiff's Millennium Stadium with tickets going on general sale tomorrow (Wednesday 24th August).
She will perform a cover of a Jackson 5 track during the gig. We don't know if the performance will be live or pre-recorded.
The event's Facebook page says: "A unique, never-before-seen performance by Beyoncé of one of her favourite Jackson 5 songs will be shown at the concert. A lifelong Michael fan, Beyoncé really wanted to be involved in this tribute concert. Due to scheduling issues she can't be there in person, but this performance is not to be missed."
Stars already signed up to be performing in Cardiff include Leona Lewis, Alexandra Burke, Pixie Lott, Christina Aguilera, JLS and Cee Lo Green.
The 'Shape Of You' singer's headline performance at Glastonbury Festival divided opinion.
