Lily Allen will perform at Glastonbury 2014.

The "Hard Out Here" singer - on the comeback trail after initially quitting music in 2011 - is the first high profile artist to confirm she has been booked for the iconic British festival, which will take place in June next year.

"I'm playing Glastonbury. It's official. I got the news yesterday. You can catch me, I'm doing an acoustic session at the Stone Circle on Sunday night," she said, speaking on BBC Radio 1 this morning.

Lily is a regular visitor to Glastonbury festival and usually attends even if she is not performing, although it is not the only festival she will be playing next summer. "I'll be doing 16 weeks of festivals over the summer and then tour," she added.

The 28-year-old star is about to release her third album, but admits it was harder to make than her first two, because she now has daughters Ethel, who turns two next week, and Marnie, ten months, with husband Sam Cooper: "At first it was really, really difficult because I was pregnant when I was making it [her new album], with my second baby. For a long time I found it really difficult and it wasn't until I stopped breastfeeding that I started to connect with myself again, so it was hard, much harder than it has been in the past."
