UPDATE: Despite her mom's confirmation, Katherine's rep updated to Radar that the couple did not split up, they were just busy with their respective modeling and football careers. In March 2014, the couple announced their engagement.
It's over for two people you wouldn't even know about if not for one creepy sports announcer.
Katherine Webb and AJ McCarron are dunzo, her mother confirmed to RadarOnline. You may remember AJ as the Alabama quarterback during the BCS Championship Game between Alabama and Notre Dame back in January. The cameras kept cutting to his model girlfriend, Katherine, with sports announcer Brent Musburger gushing about how the quarterbacks get all the beautiful women.
Unfortunately, all was not picture perfect with the couple. According to Radar, while Katherine was at the Spike TV Awards in June, AJ spent the night with a different model. Katherine walked the red carpet alone at the ESPY Awards in July.
