Rita Ora's performance at the Macy's Thanksgiving Day parade caused a stir on Twitter on Thursday, and many mocked the 27-year-old singer after she apparently got caught up in the coldest show since 1901. The video of Ora's performance shows that the track was lost to start singing his new song, "Let You Love Me", while the pre-recorded track plays in the background. The camera operators covering the event were supposedly panned to avoid any closeness of Ora's lips as she struggled to re-synchronize with the song. While Twitter was flooded with comments about the timing of Ora's lips, singer John Legend quickly came out in his defense. "Fun fact." We all have to synchronize the lips in this parade because the floats do not have the ability to handle the sound requirements for a live performance, "he wrote, and later he launched himself on Twitter to echo the Legend's explanation, saying that she always sings live at her concerts. "You know that this girl does not have lip syncing, it's not my world! Now let me go find a turkey! ", He wrote on Twitter. Singer Kelly Clarkson reportedly chose not to rely on lip-syncing despite the low temperatures, apparently telling parade officials that she brought her entire band with her because "I sing live" . Diana Ross, Martina McBride and the Sesame Street Muppets also performed at the parade. Thousands of spectators braved temperatures as low as 19 degrees and strong gusts of wind to participate in the traditional tradition and see giant balloon characters fly through the streets.
