The first preview of “Duets,” the next episode of Glee, offered a few tantalizing pieces of information: we get to see more of Chord Overstreet, we get to see Rachel and Finn (Lea Michele and Cory Monteith) sing lovingly to each other … and, we get to see some new romantic chemistry that could change things up a bit.

We’ve managed to dig up some additional information, so if you want spoilers just keep reading…

Tina and Mike (Jenna Urshkowitz and Harry Shum, Jr.) will sing together, as will Quinn and Sam (Dianna Agron and Chord Overstreet). Rumors also suggests that Coach Beiste (Dot Jones) will soon have a musical number, which may be featured in next week’s Glee installment. We can only hope! Watch the video above to get a musical sneak listen of the episode.

Meanwhile, you’ll have to wait until episode seven, “The Substitute,” before getting your first glimpse of Gwyneth Paltrow on the show. The episode will also include a “flashback” for the members of New Directions in which we’ll see younger versions of the cast. Sounds exciting!
