With a Hennessy bottle in his hand, Nas celebrated the 20th anniversary of 'Illmatic' at the Coachella music festival on Saturday (April 19). During his second-week set, the New York rhymer was joined by none other than the incomparable Lauryn Hill.

Nas performed 'Illmatic' in its entirety before bringing L-Boogie to the stage.

"Happy anniversary to all of us," he yelled to the roaring crowd.

Ms. Hill performed a rendition of the Fugees’ track 'Ready or Not' before joining Nas in a sing-along performance of 'If I Ruled the World (Imagine That).' Afterward, Nas and Hill give each other a warm embrace.

Prior to Lauryn Hill's surprise performance, dancehall/reggae star Damian "Jr. Gong" Marley performed his anthemic hit 'Welcome to Jamrock' before singing 'Road to Zion' with Nas from their 2005 collaborative album, 'Distant Relatives.'

Outside of songs from 'Illmatic,' Nas dived into his discography of hits and performed a few gems. Among them were 'Made You Look' and 'One Mic.'
