It’s down to the wire for Whitney Thore’s Big Girl Dance Class!

The star of My Big Fat Fabulous Life and her students are preparing for a major dance battle against rival school Trophy Wife Fitness. But in an exclusive sneak peek of tonight’s episode, the girls struggle with Jenzi’s choreography — who decided to show up at the last minute, much to Whitney’s disappointment.

“Jenzi arrives and I’m not in the mood to deal with her on top of everything else,” the 32-year-old says in a confessional.

The duo clashed during last week’s episode because of Jenzi’s harsh and cut-throat approach to teaching, which goes against Whitney’s style of inclusion, encouragement, and body positivity. Jenzi started to pick apart the dancers, and even threatened to cut some of Whitney’s girls from the performance. But the reality star defended her team.

“They’re going to look as best as they can look and we’re all doing it — together,” she said.
