Dannii Minogue has revealed that she became dependent on botox after her sister Kylie was diagnosed cancer and her best friend died.

The X Factor judge told The Sun that she got so stressed as her sister had treatment, that she could no longer bear to look at her face.

Dannii said: “My sister was sick, then my best friend died soon after – I felt I’d been hit by a wave.

“I couldn’t deal with the stress. I couldn’t deal with having to look at my face.

“It was a personal thing of having to get through a lot of sadness.

“At first, it was something fun I tried, then it became a necessity.”

However life has since improved for Dannii, who is dating Australian model Kris Smith. She added: “I don’t need Botox now and don’t want it. Life is just so different now.”
