Rappers Nicki Minaj and Trina celebrated their belated birthdays at Club Miami in Atlanta over the weekend and celebrity photographer Prince Williams and his ATLPICS.net team were in the house!

Nicki, who turns 25 tomorrow, and Trina, who turned 31 last week, are suddenly BFFs now that there is no other competition for the female rap crown. What I found most interesting about these pics were Nicki Minaj’s facial expression. In addition to having that fake smile and the dead behind the eyes look, she seemed to share the same facial tics that Bobby Brown is famous for.

Is Nicki Minaj on crack?

Both ladies seemed to enjoy themselves with celebs such as boxing champ Floyd Mayweather, Grand Hustle comedian Lil Duval and socialite (I don’t know what else to call her) Teyana Taylor, among others.
