When I heard that Måns Zelmerlöw had duetted with Magnus Carlsson on a new version of All I Want For Christmas Is You, I was understandably excited. Not only were two of my favourite pop boys singing a duet, but the song choice suggested Måns had come out as gay and he and Magnus were the latest celebrity couple! So you can imagine my disappointment when I heard a female voice and realised that Måns had instead duetted with AGNES Carlsson, a past Idol winner. Even worse news: They have turned a jolly pop classic into a totally snoresome ballad. But, on further reflection, Måns is far too young and cute for Magnus.
