She didn’t take the stage with Eminem as had been rumored, but Lady Gaga still commanded the spotlight with her presence during Eminem and Jay-Z’s second sold-out concert at Comerica Park in Detroit on Friday (Sept. 3).

Sporting a silver micro-skirt that blew up in the wind and a silver wig similar to the one she recently rocked on her Vanity Fair cover, Gaga threw a diamond in the sky from her elevated platform in the center of the field while watching Jay’s set, rocking out to cuts including “Empire State of Mind” and “U Don’t Know.”

Visible to the fans in attendance but protected by bodyguards, Gaga, who performs tonight at Michigan’s Palace of Auburn Hills, continuously drank from a plastic cup as fans pointed her out. After watching Jay’s set for an hour, the pop star headed backstage 20 minutes before its end.

The concert, which was also attended by “Lost” star Dominic Monaghan, featured the same batch of guest stars as the night prior with the exception of Drake. Friday’s show saw Dr. Dre, 50 Cent and G-Unit, D12, Young Jeezy, and Trick Trick help the headliners make history.
