"Miss Hilton was neither asked, nor did she give permission, for the use of her likeness in the ad, and has no further comment," her rep said in a statement.
In the campaign ad from the Republican presidential hopeful, images of Spears, Hilton and Democratic challenger Obama appear on the screen as a voiceover says, "He's the biggest celebrity in the world. But is he ready to lead?"
Spears's rep has declined to comment.
