Also, Webb was one of the Sports Illustrated swimsuit models who helped read the Top 10 list on "The Late Show with David Letterman" Monday night. The theme of the list was the top 10 questions on the application to appear in the Sports Illustrated Swimsuit Issue.

Webb read No. 2: "How would Brent Musburger describe you?"

Webb, who was raised in the Columbus-Phenix City area, achieved Internet fame earlier this year when she watched her boyfriend, starting quarterback AJ McCarron, play for the University of Alabama in the BCS National Championship.

Webb graduated from Auburn University.

The headline-making moment came about 30 minutes into the game, when ESPN's camera turned to Webb. Sportscaster Brent Musburger offered some comments best summarized as "interesting."

"You quarterbacks, you get all the good-looking women," said Musburger, whose age is listed as 73 on Wikipedia. "What a beautiful woman."

ESPN later apologized for the comments. Meanwhile, Webb gained a deluge of Twitter followers -- and a spot in the Sports Illustrated Swimsuit Issue.

Kate Upton is this year's cover model, but "Bama Bombshell" Webb gets a shout-out on the cover. The issue hit select newsstands Monday, and will appear on remaining newsstands this week. You can access the digital version here.
