If you were disappointed that Lea Michele (Rachel) and Dianna Agron (Quinn) didn’t have a duet during Glee last week — the opportunity was there in the auditorium! — here’s some great news: The two real-life friends will perform together before the season is out.

Yesterday, Lea tweeted, "Just recorded one of my favorite mashups with @alittlelamb [Dianna Agron]! Can't wait for you guys to hear it:)"

We can’t wait either. In the meantime, we can speculate: Which songs will they mash up? What are the circumstances of their duet? Could it be yet another girlfight over Finn (Cory Monteith)?
