Cher's transgender son Chaz Bono upped his security after receiving a barrage of death threats following his appearance on Dancing With The Stars last year.

Bono used the U.S. hit show as a platform to introduce himself as a man to the American public after starting out on the road to changing his sex in 2009.

He was accustomed to fundamental Christians taking aim at him during his years as a gay woman, but Bono admits it was still terrifying when the vile threats started to pour in via Twitter.com after his first appearance on the TV ballroom contest.

He tells Britain's The Sun, "That was my first death threat. I was expecting a backlash from Dancing With The Stars. It was certainly more than I expected.

"I've been dealing with the conservative religious right here for years so it's really par for the course. Thankfully, nothing serious happened after the threats but I was cautious about security."
