Sheryl Crow is disgusted by media rumours she and fiance LANCE ARMSTRONG are visiting fertility clinics in a bid to conceive a baby. Cyling legend Armstrong famously suffered from testicular cancer and had to store sperm to have children with his first wife KRISTIN RICHARD. And the ALL I WANNA DO hitmaker is outraged journalists feel they have the right to spread rumours about such a sensitive subject. She says, "I can laugh off the rumours. But in the privacy of my own home they grieve me. "They are such serious and personal topics that the fact that somebody feels they have a right to even write about them is grotesque. "What can you say? If we were going to a fertility clinic, I'm sure that I wouldn't be talking to you guys about it."
