2 Chainz is everywhere. The much-sought-after rapper, who will join Nicki Minaj on the U.S. leg of her “Pink Friday” tour, pops up on Blackground/Interscope singer Jenna’s new single “Falling to Pieces.” “I put her in the game, tattooed her name, falling all to pieces, we should pick it up again,” raps 2 Chainz, as Jenna coos over the hypnotizing beat.
