and Woody Harrelson
both experienced the magic of David Blaine's Electrified: One Million Volts Always On
in New York City this weekend.
Operating on no food or sleep, wearing a chainmail bodysuit and surrounded by over one million volts of electricity (with Intel Ultrabooks controlling the voltage), the illusionist defied death by undergoing electric shock treatment for three days at Pier 54.
Silverstone and Harrelson both brought their significant others to witness Blaine in person.
"They had an incredible time and stayed for a while watching David interact with the crowd," a source tells PEOPLE.
Harrelson couldn't get enough of Blaine's latest performance.
"He said it was a stunning experience and he came back three more times throughout the weekend," the source adds.
