Despite Mary Delgado's November arrest on a domestic battery charge against her fiance Byron Velvick, The Bachelor star from the sixth-season couple is apparently still attempting to make his relationship last.

"They are very much trying to work things out," The Bachelor host Chris Harrison said in a recent interview.

Now that The Bachelor lovebirds Matt Grant and Shayne Lamas have called off their engagement, Delgado and Velvick are the only remaining couple from the long-running ABC reality TV series still together.

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 have no wedding plans at this time, they've remained engaged.

Delgado and Velvick were at a friends' condominium watching The Bachelor's 11th season when the Pinellas County Sheriff's Office claims that the pair disagreed over whether they should leave the home.

While Velvick wanted to leave the condominium, Delgado wanted to stay, and after the pair got into Velvick's truck, things "turned physical."
