Webb's pageant biography says she was born in Montgomery and grew up in Phenix City. Webb worked for Chick-fil-A as a training director in Columbus, Ga., before moving to Los Angeles to pursue modeling. She finished in the top 10 in the national pageant.
The biography also notes that Webb studied business at longtime Alabama rival Auburn University.
Before Monday's game, Webb tweeted a photo of herself wearing a jersey with McCarron's number, her arms wrapped around the quarterback.
Early Tuesday, Webb posted her first tweet to her new followers: “So extremely blessed… (at)10AJMcCarron. Congrats to Alabama and making history! (hash)BCSChamps.”
