Gwyneth Paltrow and Cee Lo at Grammy Awards

The performance of Grammy night that everyone is talking about is the Gwyneth Paltrow and Cee-Lo Green duet. No-one could forget the song 'Forget You' and the way it was performed last night at the 53rd Grammy Awards held at the Staples Center in Los Angeles.

Cee-Lo commenced with the first half of the song, and much to everyone's surprise Gwyneth Paltrow descended the stairs to join the rapper for the second verse. "Forget You" is the song that Gwyneth recently sang in Glee - with the language obviously toned down. Although this is the second time the unlikely pair have performed the live duet of this single, last night's performance was a sensation with the crowd. And to inject a bit of variety into the show, the two were joined by The Muppets providing "backing and instrumental assistance".

Commenting on the performance, Jim Henson Company CEO Brian Henson said, "We have a live theatre show in New York called 'Stuffed and Unstrung,' and we've taken a bunch of the characters from that cast and made them into a band and backup singers for Cee-Lo. He'll be backed by puppets who will make up a very weird and cool band."

Gwyneth Paltrow's recent performance on hit TV show, Glee, has even elevated her popularity as a singer. In 2010 she starred in the country-musical "Country Strong" where she also recorded the soundtrack for the movie.Sound track:'Country Strong'

The "Country Strong" star has rallied many supporters as seen on the Twitter page. TV personality Kim Kardashian wrote on her page, "My fav part of the night was Gwenyth Paltrow! Her performance with CeeLo was crazy! And her jumpsuit was amaze."

Glee's Matthew Morrison also was very complimentary telling backstage reporters, "Oh my god! I was so excited for her. She's become a really good buddy of mine. I think the world of her, and she was so nervous for tonight because she’s not a singer. She killed it! She looked fantastic. My heart was just so happy for her. "

Despite all the pizzazz of the on-stage performance, she went home empty handed. However, Gwyneth will be seen again fairly soon on Glee in an episode during which she will perform a tango with Matthew Morrison.
