Rapper/producer Timbaland and Dr. Dre shocked students in California on Wednesday night by performing a surprise gig at their graduation party.
 
"The Way I Are" hitmaker was introduced onstage at Culver City High by Dr. Dre, who then performed hits with his guest in the school's gymnasium.
 
A 17-year-old student from the school, Saul Salmeron, tells the Associated Press, "When we walked in, we were like, 'Whoa. Is this a second prom?'"
 
Speaking during the event, which was sponsored by Interscope Records and Hewlett-Packard, Timbaland was met with cheers as he asked the crowd of teenagers, "Y'all got a curfew?"
 
And it's not the first time Timbaland has shocked fans recently - earlier this month he delivered a surprise performance at a music festival set on a farm in London.
