The humor is part of the life of John Legend and Chrissy Teigen. Through social networks, the couple did not stop piropearse and make videos that cause peals of laughter from his followers and other celebrities. By publishing so much content every day, it is sometimes difficult to find the inspiration: that’s why, to celebrate Valentine’s day, John Legend has ‘copied’ to the singer Mariah Carey. The interpreter All I Want For Christmas Is You used the day after Halloween to kick off the Christmas season with a fun performance. “What I have done so well, Mariah Carey?”, have asked John Legend with his particular version of the clip in the day of San Valentin. The response of the singer was not slow in coming: “I have nothing more to teach you”, he said in networks.
