U2 and Beyonce are rumoured to be headlining Glastonbury Festival this year.
Last week it was reported that Coldplay will be topping the bill on the Saturday night (although it's yet to be confirmed).
And now the Irish rock band and US R&B star have also been named as rumoured headliners at the three-day event, by Holy Moly.
U2 were due to perform at the festival last summer, but had to pull out when frontman Bono injured his back. Bey's husband Jay-Z previously headlined in 2007.
Glastonbury Festival runs June 22-24 and tickets are sold out.

Beyonce reveals she's excited to be headlining Glastonbury Festival this year.
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.
