THE BACHELOR, season 6 (2004): Only one fish in the sea caught Byron Velvick's attention! When ABC reeled in the pro bass fisherman as theirBachelor, producers also decided to bring back a season 4 contestant, Mary Delgado --one of the final four women who'd hoped to win Bob Guiney's heart. The Cuban-American beauty won Velvick's affections, and the season ended with one of The Bachelor's most romantic proposals (in Spanish, so Mary's parents could understand it). But their tempestuous relationship led to physical brawls and 911 calls (she allegedly busted his lip), and the wedding was repeatedly delayed. The couple split in December 2009.
