Katherine Webb And AJ McCarron Are Engaged And That Ring Is HUGE (PHOTOS)

This might break the heart of at least one college football broadcaster, but model Katherine Webb is no longer on the market.

The former Miss Alabama announced her engagement to former Alabama Crimson Tide quarterback AJ McCarron, 23, on Twitter yesterday. Webb, 24, showed off her gorgeous new diamond ring in a picture posted on her Twitter and wrote "WE'RE ENGAGEDDD!!! @10AJMcCarron."

The couple started dating in 2012, after Webb graduated from Auburn University, according to The New York Daily News.

The beautiful brunette also tweeted a close-up version of the ring and said "He designed it himself."

Next up, the couple will find out which team McCarron will be drafted for in May's NFL Draft.

Webb became an overnight star when veteran ESPN analyst Brent Musburger noticed -- and ogled -- her during the 2013 BCS National Championship Game between McCarron's Crimson Tide and Notre Dame.

"Wow, you quarterbacks get all the good looking women. What a beautiful woman, whoa!" Musburger fawned as ESPN cameras showed Webb in the stands. "If you're a youngster in Alabama, start getting the football out and throw it around the backyard with pops."
