Charlotte McKinney wins burger ad battle against Kate Upton

Model Charlotte McKinney doesn’t like being compared to Kate Upton, and the feeling may soon be mutual.

McKinney’s Carl’s Jr. ad that debuted during this year’s Super Bowl has now easily surpassed Upton’s similar 2012 commercial.

McKinney has 4 billion media impressions through the middle of May, well ahead of Upton’s 2 billion impressions, according to Carl’s.

Both ads are similarly sexy, with McKinney walking “au naturel” though a farmer’s market, and Upton making out at a drive-in with her Carl’s Jr. burger.

Both ads premiered during the big game.

Last week the Carl’s Jr. folks were in New York with Sports Illustrated model Samantha Hoopes, who is the star of its new ad campaign.

Carl’s Jr. does not use the same models twice, although the company said it is considering breaking its own rules for McKinney, our Josh Kosman hears.
