Jay-Z and Eminem headlining the first-ever show at the new Yankee Stadium is already history in its own right—even before you factor in an in-your-dreams guest list that included 50 Cent, Coldplay's Chris Martin, Dr. Dre, D12, Beyonce, Swizz Beatz, Drake, Memphis Bleek, and B.O.B. But the night's most memorable moment was provided by someone else: Nicki Minaj, who outshined Jay-Z and Kanye West by dumbing out on "Monster," two months before the song would even be released properly on Kanye's My Beautiful Dark Twisted Fantasy, and two months before her own debut, Pink Friday. If a star was born on that verse, then a superstar ready to hang with the big boys out the gate was born that night.
