Following the event, which raked in $15million for Obama's re-election campaign, actor Tobey Maguire joined the pair for the playoff.
She told People: "I was a cheerleader on the side. George and Obama were on the same team, so they both [won]. It made it easy."
Stacy also said it was "an honor" to have organized a fundraising event for the American leader.
She added: "To have the President at our house was such an unbelievable honor. I would say that there is such an energy and a presence, and I felt almost speechless."
Obama is expected to attend a benefit thrown by actress Eva Longoria and entertainer Ricky Martin in New York City on Monday (May 14).
'Glee' co-creator Ryan Murphy has also said that he will host a dinner for the politician who recently announced his support of gay marriage.
