You might think that Kristin Cavallari is all serious now, because she's like, married to the quarterback of the Chicago Bears and writing a book or whatever, but don't you forget for one second what she is best known for across seas and continents: being hot.

Believe it or not, someone forgot that fact today, and that someone was—of all people—Kristin's husband's coworker, Bears right guard Kyle Long. When asked on Twitter who he thinks is hotter—Kristin or actress Olivia Munn, who's dating Green Bay Packers QB Aaron Rodgers—Kyle fumbled.

Ummmm excuse me.

Rude.

Unfortunately, Kristin was so galvanized by the dig at her unimpeachable hotness that she accidentally revealed her natural hair color to the public.

Kyle was not swayed.

This has been 500 Days of Kristin.
