1. X Factor USA: Season 2 - Pat Ford
We're big fans of Britney here at Handbag and couldn't wait to see her on the X Factor judging panel. We thought we were the biggest Britney fans... until we met Pat Ford.
He brought flowers to give to her and arrived on stage yelling "HEY BRITNEY...".
Then the music started - Britney's 'Circus' - which he completely butchered. It got worse. Dance moves were added and a very awkward exchange at the end made this a very entertaining watch...
2. X Factor UK: Series 3 - Donna
Strong words started this audition "My name is Donna, like Madonna. I want to be as big as her" with the judges looking on incredulous.
It wasn't until Donna begun singing Madonna's Like A Prayer that the judges found out what they were in for.
The audition was stopped quickly, but Donna begged for a second chance - even saying to Paula Abdul (who was in hysterics) "Please Cheryl!" - despite the judges rejecting the opportunity to hear a second song, Donna began singing again... and it wasn't any better the second time.
3. Bulgaria's Music Idol: Valentina Hasan
This one is so bad it's amazing. We're all for hearing a bit of Mariah on talent shows, but this took her 'Without You' and revamped the song into a new version: 'Ken Lee'.
"If living is without you" became "tulibu dibu douchoo" making this one of our all time favourite terrible auditions.
4. Britain's Got Talent 2009: Dan Kahn
Another one that decided to butcher Mariah Carey's 'Without You'. Judges Simon Cowell, Amanda Holden, Kelly Brook and Piers Morgan had to endure this as the audience chanted "OFF! OFF! OFF!".
Once the song ended, however, Amanda Holden was brutally honest and told him "Can I just say - as bad as you - and you were BEYOND rubbish...". We'll let you be the judge.
5. Britain's Got Talent 2009: Clare Morton
Seemed like a lovely person and we were actually rooting for her to do well, until she started singing. At 49-years-old, Clare burst into dance moves as soon as the music start but when it was time to sing was like a lost soul.
She didn't know the words and had the lyrics on a piece of paper. Amanda, Piers and Simon were not impressed and all 3 buzzers were pushed before the chorus was over.
