Every performer dreads experiencing a wardrobe malfunction on stage but unfortunately for these pop stars, the unthinkable happened. US rocker Lenny Kravitz gave his audience more than an eyeful when his leather trousers split to expose his penis on stage but he is not the first and he certainly will not be the last.

From Fancy rapper Iggy Azalea flashing her crotch to a group of teens at a Bar Mitzvah to Toni Braxton's entire dress falling down, IBTimes UK takes a look at some of the most shocking onstage wardrobe malfunctions in music...

1. Janet Jackson's super boob at the Super Bowl

Widely regarded as the ultimate "nipplegate", Jackson, 49, was performing at the Super Bowl in 2004 when a very young Justin Timberlake accidentally ripped off part of the singer's corset, exposing her breast. TV network CBS, which aired the live sports event, was initially fined $550,000 but the ruling was overturned in 2011.

2. Nicki Minaj gives Good Morning America a startling wake-up call

The Starships rapper is no stranger to a scandal but even she surpassed herself on GMA in 2011. Hip hop's hottest female rapper was performing when her crop top slipped down to bare her breast. The network said there was a time delay in the broadcast but the photos were already out.

3. Lady Gaga pulls a Lenny Kravitz

There seems to be a pattern with leather trousers, singers and the stage. The Poker Face singer was performing in Vancouver in 2013 when she bent over slightly and split her pants, putting her bare bum on full display for the audience. Gaga was wearing black fishnet tights but, like Kravitz, she appeared to be fully commando underneath.

4. Beyonce flashes at the Super Bowl

Aside from her animated facial expressions, there was another reason Queen Bey tried to ban photos from her half time performance in 2013. The diva went full throttle with her dance moves while headlining the show but the price was flashing her lady parts to more than 100 million viewers thanks to a very tight leotard.

5. Toni Braxton almost loses everything

Now there is suffering the odd nip-slip or occasional crotch-flash but losing your dress is on another level entirely. The Unbreak My Heart singer hit the stage in New Jersey in 2013, only to have her shimmery silver dress shimmer down her body leaving her bare bum on show. Thanks to some quick thinking dancers, Braxton was able to go on with the performance but without the dress and covered up in a large blazer.

6. Iggy Azalea twerks too much at Bar Mitzvah

It was supposed to be an innocent performance for coming-of-age teens but the Australian rapper could not help but show off her twerking skills. The 25-year-old was in the middle of Booty when she split her crotch, giving her young audience more than they bargained for.

7. Bonus: Breakfast TV queen Judy Finnigan is left red-faced

When Richard and Judy accepted their award at the National TV Awards in 2000, Judy got a little too excited and accidentally exposed her bra after her coat popped open. It clearly was not too breezy in the venue as the presenter failed to notice, forcing an audience member to cover her up. Judy is by no means a pop star but this moment will always be a classic.
