Think this hot girl-group needs no introduction. They are probably one of the hottest girl groups around since, dare I say, Spice Girls? They actually released their first single in 2004 with their lead singer, Nicole Scherzinger, steaming up the MTVs. Some interesting trivial: The Pussycat Dolls had re-recorded “Don’t Cha” in Simlish for inclusion in the computer game The Sims 2 Pets. Hmm… gotta hear that.
