Eminem headlined Lollapalooza in Chicago this year and during his set brought out Bruno Mars, his Bad Meets Evil other half Royce da 5’9 along, and Skylar Grey. 90,000 fans lit up the sky with cell phones and lighters as Bad Meets Evil and Bruno Mars performed their top 10 smash “Lighters” for the very first time. Skylar later joined Em on stage to perform “I Need a Doctor.” Watch both performances after the jump
