UK rapper Stormzy has admitted he is "overwhelmed with emotions" as he prepares to become the first black, British solo artist to headline Glastonbury.

The Croydon-born artist will take to the festival's main, Pyramid Stage this Friday evening and he told his fans on Twitter: "I am (the) first, black British artist to headline Glastonbury.

"At 25-years-old, I am the second-youngest solo act to ever headline Glastonbury, the youngest being a 24-year-old David Bowie in 1971.

"I'm overwhelmed with emotions. This is the most surreal feeling I've ever experienced. I feel my entire life has lead to this moment."

He added: "Can't explain or fathom what this all is but I am 100% sure this is all God and his favour. Giving him all the glory.

"Thank you to (Glastonbury organisers) Emily and Mike Eavis for believing in me I can't wait to see you and hug you both."

Festival co-organiser Emily Eavis told BBC Radio 2: "I'm so excited about Stormzy tonight" and described the atmosphere at the festival this year as "really good".

"I don't know whether it's because we had a year off that I'm feeling it incredibly strongly," she told Zoe Ball.

"It's so lovely. People are happy in good spirits and nice to each other and there's a really good atmosphere. There's nothing like it."
