Singer Annie Lennox has written a scathing critique on the "phenomena of celebrity", taking aim at "horrible talent shows", reality Tv and "brand empires".

The former Eurythmics star is convinced the music industry changed drastically in the 1990s and has now become too entangled with brands, sponsorship and advertising.

She also insists the rise of reality Tv and competitions such as The X Factor and American Idol has forever changed the nature of celebrity culture.

In a post on her page, she writes, "Today's blog is going to be about the phenomena of celebrity. Trust me... everything changed in the early 90s... So many things changed at that point. The whole music industry turned into a completely different ball game. (I still can't quite get my head around it...)

"It's all about collusion... The collusion of music industry and fashion labels.The corporate sponsorship deals with brands... The perfume deals... The soap powder deals... The reality shows, the horrible talent shows with their stupid row of judges... Everybody's part of the feeding frenzy... Now we've got pop moguls and tycoons... kings, queens, prince... our necks ache with the discomfort of gazing up towards their Truman Show pedestals."

Lennox also insists she can't understand why anyone would want to be famous these days, adding, "I don't know what it must feel like to be followed every day from airport to car to hotel to home to restaurant to high street... Well... I've had a taste of it, and I truly hate it... There's no money worth losing your freedom or privacy for... but everybody's rushing for the golden carrot... And then... What are any of these guys famous for? What have they done? What do they contribute? Are they raising the bar in any shape or form?"
