Gwyneth Paltrow just keeps singing -- and is returning to "Glee" next week as singing substitute Holly Holiday!
We got our hands on some sneak peek pics from the new episode, titled "Sexy," showing Holly getting close with Matthew Morrison's Mr. Schuester -- who's reportedly using her reappearance as a way to make Jayma Mays' Emma jealous.
A couple of Gwyneth's songs from the episode have found their way online too, including her and Morrison's version of Prince's classic "Kiss" -- check it out below!
The episode airs next Tuesday.
