The crowd at Thursday night's 'Glee' tour stop in East Rutherford, New Jersey, got a big surprise when former 'Glee' guest star, Gwyneth Paltrow, hopped on stage, PEOPLE reports. The audience went wild when the Academy Award-winning actress appeared dressed as her character, Holly Holiday, and launched into Cee Lo Green's 'Forget You.'

Paltrow, whose appearance at the concert was taped for the upcoming 'Glee The 3D Concert Movie,' jumped around and danced with different members of the McKinley High gang.

This wasn't the first time Paltrow performed Green's hit song. In addition to belting it out on 'Glee,' she also sang it on 'Saturday Night Live' and at the Grammy Awards.

Jane Lych, aka Sue Sylvester, also made a cameo at the concert, singing alongside Lea Michele, Cory Monteith and Mark Salling.
