Adele chose last night's edition of the X Factor (well, an ad break) to share a snippet of music from her forthcoming new album, which everyone assumes is called 25 due to the fact that her first two albums are called 19 and 21 respectively (a fair assumption, I guess). According to various sources, the singer is set to appear as a guest on the talent show this season, so expect more album detail leaks and news blasts like this over the coming months.
