Glee co-stars Matthew Morrison (Mr. Schue) and Gwyneth Paltrow (Holly Holliday) are heating things up off-screen, but not in the way you might think. Gwyneth has lent her sexy vocals to a duet for Matt’s upcoming solo debut!

The pair — who seem like total beffies (and hopefully nothing more) — have recorded a duet of “Over the Rainbow” for Matthew’s album, and Entertainment Weekly has a taste of it online. It sounds much like Morrison’s version of “Over the Rainbow” from the Glee Season 1 finale, but with Gwyneth’s stellar vocals added for effect.

The track will be available on iTunes tomorrow, and Matt’s full album is scheduled for release on May 10!
