The Party Down South gang is headed to Savannah Georgia for another vacation on the new season, and though everyone is supposed to be cool with one another going into the new trip, things will be more dramatic than ever.

'PDS2' Stars Raven & Bradley Are Officially Parents!

This time around, the source of the drama will be Lyle's fiancee Santana, who will initially be an issue with Tiffany and Lauren, who learned after coming back from Florida that Santana hadn't been faithful to Lyle before his proposal-and they are not okay with it.

"I have known Santana for a long time. We're from the same town, and supposedly, Santana cheated on him while we were gone," Lauren says in an extended sneak peek for the new season. "I know about it, Tiffany knows about it. I don't want to tell Lyle about this. I could tell him and he could leave her and be depressed, or I could tell him and he'll stay with her and keep getting hurt. And at this point, I don't know what to do."

However, it appears the two will eventually let Lyle know about his fiancee's actions, and it will cause some problems with the group, especially as Tiffany continues to stand her ground and maintain that she will not support Lyle if he decides to still marry Santana, even knowing the truth.

"I ain't going to that wedding," she says to Mattie.

However, this brings Daddy into the fight as well, when he starts defending Lyle and telling Tiffany to stay out of it and be supportive.

"Get off his ass, that boy's taking this s**t like a champ," he says.

But a visit from Santana will eventually make everything worse-and after a nasty no-holds barred fist fight between she, Lauren and Tiffany leads to Lyle being sent to the hospital when he has trouble breathing and winds up clutching his chest-the rest of the roommates could quickly get on board with the anti-Santana sentiment.

"She's making this boy go to the freaking hospital," Mattie says in the clip.

Party Down South season five premieres January 28 at 9 p.m. on CMT.
