The Fusion Festival takes place on August 31 and September 1 in Cofton Park and also features the likes of Union J, Wiley, Amelia Lily, Wretch 32 and Conor Maynard, which is all very exciting.
If you're after a quote from Jessie J that's been plonked in a press release, then look no further:
"I can’t wait to perform at Fusion Festival, it’s exciting to be headlining a brand new UK festival with such an amazing line-up, it’s one of the performances I’m most looking forward to this summer. It’s amazing that the festival is donating £5 from each ticket sale to The Prince’s Trust, it’s one of the charities closest to my heart and makes me even more proud to be on the line-up. Roll on August 31st, it’s going to be BIG!"
