It's official: Nicki Minaj did not endorse Mitt Romney in a recent rap.

The flamboyant rapper confirmed Monday on Twitter that she was taking literary license when she referenced the Republican nominee for president. Some took her words to mean she was backing President Barack Obama's opponent.

Not Obama, though, who told radio station WPYO-FM in Orlando, Florida, that he didn't think it was a Romney plug, adding: "She likes to play different characters."

In her tweet, Minaj thanked Obama for understanding "my creative humour and sarcasm," then noted: "the smart ones always do ... (asterisk)sends love & support."

Minaj rapped the verse in question while making an appearance on the Lil Wayne mix tape track Mercy.

A message sent to Minaj's publicist was not immediately returned.
