Earlier this week it was rumoured Bey would be performing at the summer event alongside U2 and Coldplay.
Although organisers have yet to confirm Knowles' appearance, the R&B star has revealed the news herself.
"This really is the biggest festival in the world and I cannot wait to perform there," Beyonce told Billboard.
"Everyone who attends is really appreciative of music and is in such a good mood that entire weekend. I'm pumped just thinking about that huge audience and soaking up their energy."
In 2008, the singer's husband Jay-Z headlined the festival. The event is sold out.
