The other man in Lil' Bit's life is set to finally make an appearance at the house on Party Down South, but his arrival won't necessarily bring his girlfriend and her former hook-up good things.

Lil' Bit's boyfriend, Grant, will finally make his way to Athens after endless phone calls with her, but the cast won't necessarily be fans of him after he arrives-and Daddy could cause trouble if he gets drunk and starts spilling the secrets Lil' Bit may have been keeping from Grant.

In a preview clip for the Thursday, July 17 episode, Daddy will ask Grant what his feelings for Lil' Bit actually are-and he won't particularly like the answer.

"You actually like Lil' Bit don't you?" he asks him in the clip.

"I love her," Grant replies.

Daddy isn't happy to hear this, and begins wondering which one of them was the last one to actually have a chance to sleep with Lil' Bit, since he maintains the two of them had hooked up the day before arriving in Athens.

"I wonder who banged your girl last, me or you?" he says in the clip.

If Daddy spills the beans about the last time he hooked up with Lil' Bit, it could mean the end of her and Grant.

Meanwhile, after Mattie was on uncharacteristically good behavior for most of the season, she will finally get drunk enough for her alter ego, Martha, to finally arrive on the scene.

However, while Martha is always ready to party, the kinds of trouble she gets into while taking over could wind up actually ending Mattie's party after she appears to pass out from drinking too much.

"We went from having fun, fun, fun, to needin' 9-1-1," Lil' Bit says in the clip, as an ambulance is seen speeding up the road.

Party Down South airs Thursdays at 10 p.m. on CMT.
