Happy Birthday to one of the Queens of Rap! Cheryl "Salt" James of Salt N Pepa celebrates turning 51 today (March 28) and the diva is still rocking the mic and the stage.

Salt N Pepa had one of the biggest hitmaking runs of the 1980s and 1990s and Salt actually wrote and produced one of their most beloved hits in 1990s "Expression." With classics like "Push It," "Whatta Man," "Let's Talk About Sex" and "Get Up," you'd be hard-pressed to find many hip-hop groups with more commercial success than Salt N Pepa.

Last summer Salt, Pep and Spinderella were honored as part of VH1's Hip-Hop Honors: All Hail the Queens celebration. But today is Salt's day, so we salute the lovely and talented Cheryl James!
