Sheryl Crow leaving after having lunch at the Ivy restaurant in West Hollywood. Los Angeles, California - 13.12.07

The 45-year-old was diagnosed with breast cancer in February 2006 just days after ending her three-year relationship with fellow cancer sufferer and cyclist Lance Armstrong.

And the star believes the events sparked an ever-present paparazzi frenzy that put a strain on her recovery.

She says, "Having 100 paparazzi outside my gate at all times because of the terrible things that were happening, it really spoke to me about who we are.

"If this is what makes people want to buy magazines - someone at their absolute lowest - that is a very sad message. I found the whole experience was very difficult. I went from being linked with one of the most famous cancer survivors to then begin diagnosed with cancer."
