Jessie J's "Domino" was actually a Katy Perry song? Jessie's voice sounds almost exactly like Katy's and the style of the actual song sounds like something Katy would do. Anyone else agree?

Yeah definitely, I was convinced it was Katy Perry at first.

No you're not the only one.

Not really. I don't get this Katy perry style...she doesn't really have one to be honest.

Thought this as well and there is a reason for this - Dr Luke
