Jessie J continues Britney talk, says "people could be surprised"

Yesterday we told you about Jessie J, the co-writer on Miley Cyrus's "Party in the USA", who was working on a Britney song. Today, we got some new info.

In an interview with the UK's "Sun" she explains:

"I received the beat to work with and it's amazing. It's pretty cool. I don't think it will be what people expect.

"It's more British than you would expect but with the Britney swag. People will be surprised. It could be the most amazing thing I've done."

Today, she tweeted, hoping to clear up any confusion saying:

Can I just say I NEVER said I wrote Britneys next single. I SAID I have been sent a BEAT to write a top line on. That DOES NOT mean it will be used nor does it mean it will be the single. #cool?
