PIC: Gwyneth Paltrow Crashes Glee Concert!

Gwynnie's still a gleek!

Though her two guest appearances on Glee aired months ago, Gwyneth Paltrow's still got love for her new McKinley High pals.

On Thursday, Paltrow, 38, surprised fans at New Jersey's IZOD Center with a performance as part of the Glee Live! concert tour.

Clad in a black top, gray skirt and boots, Paltrow -- who last appeared as Holly Holliday in March -- jammed with Glee's New Directions for Cee Lo Green's "Forget You."

Jane Lynch was also in attendance at the East Rutherford, N.J. show, which was taped for the upcoming Glee Live! 3D concert film.
