While speaking about her decision on Radio 1's Breakfast Show Allen told DJ Nick Grimshaw that her husband is in charge of ticket allocation and that she has "quite a lot of blaggy friends who hit me up for stuff all the time and never really appreciate it."
"I have all the calls, 'Can we have some tickets?'" said the 29-year-old, adding that this year the couple decided to give the passes to villagers.
"There's, like, 25 kids from Canham who have never been to Glastonbury and who are going to have such a shock, and all my showbiz mates are like, 'Er?'"
The Glastonbury festival is a music fair that also features dance, comedy, theatre, circus, cabaret and other arts. This year's event will take place from June 25 to the 29.
"I go in hard. I was six-weeks-old the first time I went," Allen said of the festival. "I mean I would trade Christmas for Glastonbury."
"I didn't go once," she shared. "But yeah I've been every year, even when I was preggers."
