This year's Hot 97 Summer Jam didn't only feature Young Money-related controversy. There were, as expected, plenty of surprises. That was particularly true during Nas' set, which featured an appearance from Lauryn Hill. She proceeded to run through "Ready or Not" and "Lost Ones" with Nas serving as hype-man before he took over to perform "If I Ruled the World." You can watch that performance below.
