Jessie J is keeping schtum about one the ‘biggest projects she has ever done’ and we really want to know what it is!

Jessie is currently in LA to perform shows for her American fans and to work on a US version of her second album Alive.

The It’s My Party Singer told Capital FM that her new project is major and and compared it to her performance alongside Queen at the London 2012 closing ceremony.

I’m excited. I’m going into the studio. Working, writing a single. I’ve been offered one of the biggest deals ever in my life, that I’m writing a single for.It’s not a movie but it’s one of the next biggest things from the Olympics, for me. I’m excited! I’m very ready to go and do it well and come back and go, ‘Haha!’

So its not a movie, it’s almost as big as the Olympics… Hmm, will she be releasing a secret single in the middle of the night like Beyonce? Or maybe she’s recording a theme song for the new season of Game of Thrones? That’s pretty big.

Just tell us what is is Jessie!
