John Mayer Performs, Fakes Pal's Hospital Trip
The two began the night at Hollywood hot spot My House, where they were seen sharing Corzo tequila shots straight out of the bottle before Mayer launched into an impromptu show.
"The place went nuts!" says a clubgoer of the singer's performance of his hit "Your Body Is a Wonderland" and rendition of TI and Rihanna's "Live Your Life."
But the night ended with the two stumbling out of the club and, according to Mayer's Twitter, to a hospital: "In triage at Cedars with @Robdyrdek. When the contents of his stomach hit that silicon bag and we all saw it, we just broke into applause."
Not to worry, Dyrdek, who was celebrating the release of his fim Street Dreams, didn't really have to get his stomach pumped. "It was fake, they were just having fun and screwing around for publicity," a source tells PEOPLE. The skateboarder/reality star was up and running the next day, Tweeting: "A funny night out with @johncmayer."
