Nicki Minaj

Nicki revealed in an interview with that she also underwent an illegal butt injection procedure.

Nicki said: "It's not that you go to a doctor, a professional person. No, it's some random person.”

The 40-year-old rapper decided to go ahead with the procedure because of the penchant for ladies with serious back in hip-hop culture.

She added: “[Lil'] Wayne, he was always talking about big booties. Wayne would have a new chick in the studio every session. It was always a new big booty there. They were his muses."

Fun fact: Nicki sampled Sir Mix-A-Lot’s 1992 hit track ‘Baby Got Back’, known for the lyrics "I like big butts and I cannot lie", on her hit 'Anaconda'.
