Last week, The BoomBox mentioned a little rumor that Beyonce would be performing at Glastonbury this year. Turns out the rumor is true. The 'Single Ladies' singer released a statement via Columbia Records confirming her headlining spot on the last day of the giant U.K. music festival.

"This really is the biggest festival in the world and I cannot wait to perform there," Beyonce said. "Everyone who attends is really appreciative of music and is in such a good mood that entire weekend." She's got that right. Tickets for the festival -- hailed the "largest green field music festival in the world" with a capacity just under 200,000 attendees -- went on sale last October and sold out in four hours, according to the BBC. During the weekend that the festival is held, it temporarily becomes the third largest city in southwest England. Beyonce will perform a 90-minute set on the fest's biggest stage, the Pyramid Stage. "I'm pumped just thinking about that huge audience and soaking up their energy," she continued.

Glastonbury 2011 goes off June 23-26 at Worthy Farm, Pilton, with an estimated 350 acts gracing 27 stages. The rest of the line-up will be announced in the spring. Coldplay have also confirmed their headlining spot for the 4-day fest, while U2 are also rumored headliners.

In the meantime, Beyonce is up for two trophies -- Best Pop Female Vocal Performance ('Halo' (Live)) and Best Pop Collaboration with Vocals ('Telephone' with Lady Gaga) -- at this weekend's 53rd Annual Grammy Awards. They air live Sunday (Feb.13) on CBS beginning at 8PM ET.
