Barack Obama has asked Jennifer Hudson
to sing the national anthem on Thursday – the day of the presumptive Presidential candidate's much-anticipated address to the Democratic convention in Denver, her rep tells PEOPLE.
"His reps called and said we'd love for you to sing the anthem on Thursday," Hudson's rep tells PEOPLE. "She's thrilled and excited. It's a tremendous honor."
The DNC will not comment about Hudson's performance until the official schedule is announced.
Oscar winner and Sex and the City
movie costar, whose self-titled album will be out Sept. 30, has previously expressed a desire to help the Obama campaign.
"I'm so proud and excited for him," Hudson, 26, told E! Online about Obama in June. "I haven't gotten a call from them yet, but he does have my support."
Hudson will not be the only vocalist Thursday. Bruce Springsteen is scheduled to close the convention that night.
