It seems like love is in the air again for fan-favorite couple Brittany (Heather Morris) and Santana (Naya Rivera), who are making their welcomed return to the FOX hit "Glee" Season 6.

Despite a recent Instagram photo of the two actresses pictured under a "No PDA" sign at McKinley that supposedly nixed any affection between the two and put their smooch to a halt, there might be a new development. It doesn't seem like the lovely duo will be apart for long. Last week, Rivera reportedly Instagrammed a photo of her and Morris cozying up on set and captioned it, "Brit and San."

The two "Cheerios" might just drum up more cheers and take a walk down the aisle!

On Oct. 6, Rivera, 27, sent out a curious tweet that sent 'Gleeks' abuzz in the Twittersphere about the potential nuptial between the two.

The talented Latina actress tweeted:

Will the speculation that Santana will ask Britt to marry her in an upcoming episode come true? While there's no confirmation on a proposal just yet, WetPaint points out most "Glee" fans welcome the commitment and celebrate them as a couple.

The other question to ponder is what brings Brittany and Santana back to McKinley in "Glee's" final season? Inquiring minds want to know, but for now will have to keep guessing.

Stay tuned for more "Glee" Season 6 teasers because 2015 -- when the season debuts -- is quite a ways away!
