After his star-studded Madison Square Garden show earlier this month, everyone was guessing who would be Jay-Z’s special guests at his Staples Center gig. The Roc star shared the stage with Swizz Beatz and his tourmate Trey Songz during his “BP3” concert in L.A. on Friday (March 26). Swizzy hyped Jiggaman on his production “On to the Next One,” while Trigga guested on “Heart of the City (Ain’t No Love)” and “Already Home.”
