The party's over! Tiffany Heinen breaks down in tears over saying goodbye to her costars during Party Down South's season 5 reunion, as seen in Us Weekly's exclusive sneak peek at the series finale.
In the CMT show's clip, Heinen, 28, reveals the off-camera support that her fellow cast members have provided to her and her family.
"I have one brother, and then I get introduced to all these people who mean more to me than you all could possibly imagine," she tells host Christine Lakin.
"My dad's sick and battling cancer right now ... and every single one of them check up on me, check up on my dad — and that means a lot to me, you know?" Heinen continues. "Because it wasn't just about them becoming my family. They became a family's family. We're all family, and it sucks so bad to say goodbye."
Watch the emotional clip in the video above.
Party Down South's series finale airs on CMT Thursday, April 7, at 9 p.m. ET, followed by the reunion at 10 p.m. ET.
