Santana, is that you?!
In the Instagram photo, Rivera is pictured in a sparkly red bra, red bottoms and knee-high black boots. She also sports a black hat over her voluminous dark hair.
This is the second behind-the-scenes photo from the highly anticipated episode, which airs in March. The episode's director, Paris Barclay, shared a photo on Twitter of himself with returning stars Mark Salling and Dianna Agron, as well as Gossip Girl's Chace Crawford, who will play Quinn's beau.
Glee returns with new episodes on Tuesday, Feb. 25 at 8/7c on Fox. What do you think of Rivera's look?
