'The Glee Project': 'Sexuality' Episode Preview (EXCLUSIVE VIDEO)

If you want to succeed on "The Glee Project," (Tuesdays at 10 p.m. ET on Oxygen), you have to be confident in your sexuality, which is why this week's theme sees the contestants channeling their inner Santana for a sultry mash-up of "Milkshake" and "Moves Like Jagger."

The contestants will take tips on bringing sexy back from "Glee's" Naya Rivera and they'll be put through their paces by choreographer Zach Woodlee for a suitably saucy dance routine. HuffPost TV has an exclusive preview of their rehearsal above. As you might expect, a few of the contenders struggle with the challenge more than others ...

The week's theme won't be the only reason temperatures start to rise, since the episode will also see a certain couple growing closer, with their flirtation even coming to the attention of vocal coach Nikki Anders. (Good thing the week's focus isn't on "subtlety.")

"The Glee Project" airs Tuesdays at 10 p.m. ET on Oxygen.
