What would happen if you mixed Katy Perry with Rihanna and added a healthy dash of Lily Allen and Amy Winehouse? Why, the next powerhouse pop star from the U.K., Jessie J!

I went gaga over her pop-R&B sound and spicy ‘tude at the singer's recent NYC debut showcase, and my instant affection is predictably justified with the reception to her infectious single, "Price Tag," (co-penned by Bruno Mars' "Grenade" songwriter Claude Kelly) and its companion video featuring B.o.B.

The track was just released in England yesterday and immediately rocketed to #6 on the iTunes chart, this while her first hit there, "Do It Like A Dude," sits at #2.
