Best music pictures of the week, including Little Mix, Zayn, Adele, Madonna and more

It's been a bad week for everyone's favourite megastar-next-door Adele, who had to cancel a concert because of a bad cold, but a slightly better one for Madonna, celebrating her 58th birthday in typically raucous style. Oh, and it's a happy anniversary to Little Mix – five years since they were formed on The X Factor.

Get busy with your best clicking finger and take a look at the big week's pop stories in pics, including a chart diva takeover of BBC ballroom contest Strictly Come Dancing, Zayn's most unusual look yet and – GASP! – cover art for the new Gaga track. We can't even.
