ED SHEERAN performed an acoustic cover of CHRISTINA AGUILERA'S racy song "Dirrty" during an appearance on BBC Radio 1. (Here's video.) He also tried to do the WEATHER for the show. He said, quote, "The weather outside is brisk. If you walk out you will get very, very pink cheeks very quickly. You will need some lip balm because your lips will dry and . . . that will happen. Also there is a chance that you will step in a puddle today, so please do not wear slippers outside." (Here's audio.)
