Gwyneth Paltrow performed 'Forget You' at the 'Glee Live! In Concert!' show at the Izod Center in New Jersey last night (16.06.11).
The actress - who has appeared in the musical TV drama as substitute teacher Holly Holliday - performed a rendition of Cee Lo Green's 'Forget You' at the show at the Izod Center in New Jersey and sent the audience into a frenzy.
Gwyneth's shock appearance came as Naya Rivera was giving a speech boasting how her character, cheerleader Santana Lopez, had been voted the sexiest girl in glee club only for the Oscar-winning actress to burst on stage in high stiletto boots and a short skirt to declare "oh, not so fast!"
Gwyneth, 38, wasn't the only unannounced performer on the night. Jane Lynch performed as cheerleading squad coach Sue Sylvester. In other concerts on the tour the segment featuring Sue was a recording.
The New Jersey show was filmed for the 3-D concert movie which is being released later this summer.
'Glee Live! In Concert!' heads to the Nassau Coliseum in Uniondale on Saturday (18.06.11) for the final date of its North American run before heading to the UK next week.
