The 'Domino' star has taken to the stage at Wembley Stadium ahead of today's event.
Jessie J has kicked off the Summertime Ball soundchecks today (9th June) as she arrived early at Wembley Stadium.
The 'Who You Are' singer is making her third appearance in a row and couldn't hide her excitement on the way to North London.
She wrote: "Today is going to be a great day! @958capbreakfast #STB I'm on my way for my earliest sound check ever! Lol! Woooo!"
The singer's distinctive notes were echoing round the empty stadium, with fans already queuing outside from last night in anticipation for the show.
This year's Summertime Ball will also feature the likes of Taylor Swift, Robbie Williams and The Wanted.
PSY will also be on the line-up with first timers Union J, James Arthur and Duke Dumont also at Wembley.
