With her hardcore posturing and sexually explicit rhymes, rapper Lil' Kim blazed a trail for other like-minded and liberated female MCs in the '90s and beyond. Beginning with her 1996 debut Hard Core, she notched a trio of platinum-certified albums, and scored a global number one hit in 2001 with "Lady Marmalade," a high-profile collaboration with Christina Aguilera, P!nk, and Mya.
