The couple met when the sixth season was filmed in 2005. Velvick proposed to Delgado in the show's finale. While the couple has yet to wed and delayed their wedding plans several times, they've remained engaged over the last three years.
Delgado and Velvick were at a friends' condominium watching The Bachelor's eleventh-season After the Final Rose special when the Pinellas County Sheriff's Office claims the pair disagreed over whether they should leave the home after the couple they had been visiting with began arguing.
While Velvick wanted to leave the condominium, police alleged Delgado wanted to stay, and after the pair got into Velvick's truck they "became involved in an argument which turned physical."
Delgado then struck Velvick's mouth -- causing the upper left side of his lip to split. Velvick went back inside the condominium to clean-up while Delgado waited in the truck, which is when the former The Bachelor star called police.
Velvick didn't want to press charges and also did not want his injuries photographed, but Pinellas County deputies still determined a crime had happened and Delgado was arrested and charged with domestic battery.
While the charges have since been dropped, Harrison said it was a difficult situation for the couple and everyone who knows them.
"It was really unfortunate to see her in the whole prison outfit," Harrison told Us. "He never meant for it to get that far."
