Glee‘s much-talked-about 100th episode won’t air until March, but Naya Rivera is already heating up the set.

The star posted a sexy behind-the-scenes photo to Instagram on Tuesday, captioning it “#Glee100.” Rivera is seen in skimpy red lingerie and thigh-high black boots.

Her buzz-worthy, honey-colored locks – which she debuted at the People’s Choice Awards – are gone, replaced by a burst of curly dark hair tucked under a hat.

We know one person who’s probably drooling over the burlesque-like post: rapper Big Sean, Rivera’s fiancé. Considering the two both love social media (they even met over Twitter), we’re assuming he’s seen the hot snapshot.

No word on what Rivera is singing in her scandalous costume, but one contender is “Toxic” by Britney Spears. According to the episode’s fan-voted song list, the 2003 hit will be performed by Santana (Rivera), Brittany (Heather Morris) and Quinn (Dianna Agron), known by Gleeks as the “Unholy Trinity.” Glee‘s full cast first did a rendition of “Toxic” in season two.

Rivera’s revealing photo isn’t the only sneak peek of the 100th episode. Earlier this month, Glee producer Paris Barclay Tweeted a picture of Agron and guest star Chace Crawford, confirming the Gossip Girl actor will return to TV as Quinn’s love interest.
