Chris Rock performed in front of royalty Friday night ... he told jokes to Kim Kardashian and Kanye West.

Kim and Kanye attended Chris Rock's Total Blackout Tour in Hollywood Friday and took a photo with Chris and his girlfriend Megalyn Echikunwoke backstage.

Kanye is no stranger to Rock's work -- he featured him on his song 'Blame Game' back in 2010 and has known him for years.

That wasn't the only comedy royalty on hand ... he also posed for a photo backstage with Eddie Murphy.
