Adele Performs Tribute To George Michael

Adele led a touching performance in tribute to the late George Michael, however the diva had to stop her performance in the middle. Adele was upset with the performance and demanded to start it over. Although Adele continued with a flawless performance and received a standing ovation from the audience, she did not look pleased. Unfortunately, this is not the first time that Adele has run into problems with Grammy performances. Last year Adele encountered sound issues and sang of key for the entire song.
