Leona Lewis says she is excited to be singing at the FA Cup final between Arsenal and Hull City at Wembley on Saturday.
The former X Factor winner, from Islington, will sing Abide With Me and the national anthem prior to kick-off.
“I’m so excited, I'm really looking forward to it,” the 29-year-old said.
“I know it’s going to be a crazy atmosphere there so it’ll be fun. I’ve never done anything like it before so it’ll be a cool experience for me.”
Arsene Wenger has suggested the ticketing allocation for the FA Cup final at Wembley could impact on the atmosphere.
Arsenal and Hull will receive 25,000 tickets for the final at the 80,000-seater national stadium, with the rest of the tickets passed to their 'football family and Club Wembley members.
"One of the charms of the FA Cup final was always that the stadium was reality divided in two," the Arsenal manager said.
"It's a shame that it doesn't happen any more because that was always an absolutely fantastic atmosphere.
"I remember I have been at European Championship finals of the nations and World Cup finals and always there's a little bit of a lack of atmosphere because it is so divided. I think the atmosphere will lose a little bit."
