John Krasinski of NBC's "The Office," a fellow son of the commonwealth, will also welcome donors to the May 21 event at the Santa Monica, Calif., production company owned by "Star Trek" producer J.J. Abrams.
It won't be all celebrities at the party, The Hill noted. Two tickets will be issued in a raffle among donors who chipped in $5 or more. The campaign will pick up the travel costs to get the luck winners out to Los Angeles.
Warren has been on a financial roll in her campaign to unseat U.S. Sen. Scott Brown, R-Mass., The Hill said. She pumped nearly $7 million into her war chest in the first quarter of 2012.
