Rapper Nicki Minaj ended the dispute Monday over whether she endorsed Mitt Romney in a rap song released last week.

The pop star, rumored to be a new judge on "American Idol," seemed to endorse the Republican nominee, while taking a shot at President Obama on the eve of the Democratic convention.

“I’m a Republican voting for Mitt Romney, you lazy bitches are f------ up the economy,” she rapped on "Mercy," the fifth track on the Lil Wayne's "Dedication 4" album.

But there was some speculation that the line was not intended as an endorsement, but rather was Minaj in character as one of her alter egos.

Obama, clearly aware of the song, said as much on Monday while alluding to the “characters” she plays in her songs.

"I don’t know what’s going on there," he told “The Obie & Lil’ Shawn Show” on Orlando radio station Power 95.3.

On Monday, Minaj said that the line should be attributed to one of her alter egos.

She later added that she was grateful for the attention from the White House.
