Check out Jessie J performing her new track, "Price Tag" which on the original version we got B.o.B dropping in on. As we saw the other day he also appears in the video, but recently Jessie performed for MTV 'Brand New for 2011' and in the performance UK act Devlin stepped up to the Mic to fill in the gap where B.o.B. was om the recording. Catch the interesting performance up at the top. No doubt we'll be seeing plenty more of Jessie this coming year and hopefully a little more of Devlin too. Enjoy.
