Naya Rivera's New 'Glee 100' Pics Drop Hints

Naya Rivera is easily the best part of Glee this season so when she posts photos and tweets from the set of the show's highly anticipated 100th episode we're paying attention, close attention to every tiny detail. Even though we've been bombarded with Glee news since the show went on hiatus in December and we were prompted to vote for the 100th episode's set list when Rivera posts, we're still interested in learning more. And apparently, all of the show's fans feel that way.

The actress who's played Santana Lopez on the show since 2009 posted two on-set photos of herself in costume (or lack thereof) on her Instagram account on Jan. 21 and 22. Beyond the obvious, that she's got an unbelievably rocking body, it's her costume that's got Glee fans' imaginations running wild (and by wild we mean straight towards Britney Spears) about which number she could be performing.

The actress is killing it in some seriously big hair, a hat, and tiny black and red lingerie and it's only reinforcing what some fans are saying and hoping for on Twitter — that Santana, Brittany, and Quinn will be performing Britney Spears' "Toxic."

Rivera's also been tweeting up a storm about what she's been up to on the set of "100" including this tweet from earlier in the week that's definitely fueling the "Toxic" theory fire as well:

Well, at least we know for sure that she's reuniting with Quinn and Brittany, which is awesome even if Britney Spears isn't involved. What could be more unholy than a lingerie-clad performance of "Toxic"? I'll answer for you — nothing.

And here are the two photos from her Instagram that have got us even more excited about "100" than when we found out Dianna Agron and Mark Salling were returning for the episode:

We hope some fans had the sense to vote for a Britney number when Ryan Murphy asked them to choose the setlist for "100." Fingers crossed. If there's anything Glee does well, it's Britney, bitch.
