Katy Perry's Super Bowl halftime show support act Missy Elliott has been announced as the Sunday headliner for this year's Bestival.
That's what that picture above is referring to, 'FYI'.
"I'm very excited to be performing at Bestival this year!" mused Elliott in a statement (as quoted here).
"I can't wait to see all my fans I haven't seen in some time… New ones and my day one fans! We are gonna have a blast together! Bring your dancing outfits and kicks!"
She means trainers.
Bestival organiser Rob da Bank has added the following words: "Needing no introduction Missy is the epitome of hip-hop royalty, the first lady of party-starting club bangers and a downright legend. I cannot wait to watch the most successful female rap artist ever to Work It at Bestival 2015!"
'Work It' is one of her songs, that is why those words have capital letters in Rob's statement.
The festival takes place on the Isle of Wight from September 10 — 13. There's more information right here.
