Rock was slapped by Will Smith in the middle of an Oscars comedy bit and an angry fan launched at Dave Chappelle during a comedy show at the Hollywood Bowl earlier this year. News broke this week that Dave Chappelle is teaming up with Chris Rock for a show at the London-based O2 theater. The show won’t go down until September 3, but tickets will go on sale much sooner, with Ticketmaster noting a pre-sale for tickets started on June 9th and the full general sale starts on June 10.
