Glee Will Break Our Hearts With Marina And The Diamonds?!

Rumor has it that Marina and The Diamonds is getting the Glee treatment.
Lea Michele sneakily tweeted:

A tease of what I’m recording with @alxanders right now…. 😉 twitter.com/msleamichele/s├óΓé¼┬ª

Does that photo say “Brody + Rachel + Marina And The Diamonds”??? WE THOUGHT SO.
But does the catchy break up song How To Be A Heartbreaker—sung by Lea and Dean Geyer— mean the end of Rachel and Brody???
Didn’t they just move in together??!
We wouldn’t be too sad about it though, because the potential split also means hope for a Finchel reconciliation. RIGHT???
We’ll have to wait and see when the episode 16 airs in March!!!
Ch-ch-check out the original version of the spunky tune (above)!!!
