Jay-Z and Mary J. Blige have been making beautiful music together ever since the R&B diva added some serious soul to 'Can't Knock the Hustle' off the hip-hop mogul's debut album, 'Reasonable Doubt.' Now the pair will share a stage when they kick off the 'Heart of the City' tour beginning March 22 in Miami. With only 10 dates confirmed, the pair are set to play 26 shows across the country in support of their latest releases.

Jay-Z released his 10th studio album, 'American Gangster,' which debuted at No. 1on the Billboard 200, scoring Jigga his 10th career chart-topping album, in November 2007. Blige dropped her eighth studio album, 'Growing Pains,' in December 2007.

"The [songs] we're playing are the soundtracks to people's lives," Jay-Z said in a statement. "We've poured our hearts out many a night in the studio and look forward to going one step further on stage."
