Adele has performed in front of audiences around the world, so one would think the singer would look stage fright right in the eye and laugh in its face. Apparently, she has her limits. News broke that the 'Rolling in the Deep' songstress declined an invitation to appear at next year's Glastonbury festival.

76-year-old Micheal Eavis has turned the U.K. festival into one of the most popular summer music destinations in the world. Glastonbury is taking a break this year, partly because of the shortage of portable toilets and security staff due to the 2012 Summer Olympic Games in London. Eavis wanted to book Adele for the event's return in 2013, but she couldn't bring herself to accept the offer.

"She knows that we want her anyway but she doesn’t want to do a thing our size," the farmer told British magazine Metro. "Going on the Pyramid Stage I think is a bit daunting in front of 80,000 people. It’s a bit much, really."

Adele may not be belting out her hits at Glastonbury, but she makes sure to attend every year. Eavis says the chart-topper will be at the top of the guest list for next year's edition. "She comes every year usually, and has her own little party."
