The singer will be performing at the summer music festival in August and, according to our source, he'll be celebrating in style at the exclusive Louder Lounge afterwards!
Olly will play the Chelmsford leg of the festival on Saturday 22, August, and has asked organisers of the Louder Lounge to make sure the champagne is flowing!
He's reportedly bringing his X Factor co-host Caroline Flack and the new presenter of Xtra Factor - ooh, does that mean we will know by then who is taking over from Sarah-Jane Crawford?!
An insider told us: "Olly has told organisers he's bringing Caroline as his guest and also the new Xtra Factor presenter although nobody knows who it is yet!
"He's planning on having a big party backstage in the Louder Lounge and has asked for loads of champagne to be delivered so they can toast his performance in style!"
Can we come along as well, please?!
