Whitney Houston's appearance on The X Factor was as notable for the wardrobe malfunction that saw her dress start to fall down and for her uncomfortable interview with Dermot O'Leary as it was for her great vocal performance.

The X Factor is making a habit of rehabilitating troubled pop stars, because just the week before Robbie Williams was disconcerting us with his alarming stare - after getting flustered when a door to the stage failed to open and he had to force it.

At least Robbie stayed on the stage though, which is more than can be said for poor Peter Andre at T4 On The Beach in July. He managed to slip on a flight of steps and tumble into the photographers' pit. We can only assume he landed on top of them - and that's why they didn't get a picture of it.

Taylor Swift was having such a lovely time thanking everyone for her best video award when suddenly that nasty Kanye West appeared and grabbed the mic, to let everybody know that "Beyoncé had one of the greatest videos of all time". Poor girl.

It was quite a coup to get Miley Cyrus on Ant and Dec's Saturday Night Takeaway back in February. It was just unfortunate that she completely forgot the words halfway through performing her new song.

Yes, that is David Bowie with a lollipop stick in his eye. A fan threw the kids' sweet at the stage during a concert in Denmark and it freakishly got stuck between the pop legend's eye and eyelid.

Fergie had a rather embarrassing "wee accident" while performing with the Black Eyed Peas back in 2005. The girl's a trooper though, because she just carried right on - and even squatted down so this photographer could get a good shot.

P Diddy (or whatever he's calling himself this week) has a penchant for stage diving when the mood takes him. Unfortunately the crowd at one gig in Ibiza decided to get out of the way sharpish - cue one rapper with a rather bruised ego.

The same thing happened to Coolio at a gig at Staffordshire University earlier this year, except that the crowd added insult to injury by robbing him of his valuables as he lay winded on the floor.

In the event that gave the world the phrase "wardrobe malfunction", Janet Jackson showed the world her right boob during a Superbowl break performance with Justin Timberlake. She swiftly covered it up, but the fact that she was wearing a fancy nipple decoration made many suspect it was a stunt.
