Whitney Houston "hated" 'X Factor' finalist Danyl Johnson.
The 27-year-old teacher says he infuriated the 'I Will Always Love You' hitmaker when she appeared on the show as he chose to sing one of her unreleased album tracks, 'I Didn't Know My Own Strength'.
He admitted: "Whitney absolutely hated me. She was the worst guest."
Danyl has also revealed he battled testicular cancer when he was 11 and "feels passionate" about encouraging young boys to have check-ups.
He said: "I have had many visits to hospital. Mostly it was to do with sports and arts injuries but when I was 11 they found cancerous cells in my scrotum.
"It was a scary time and I came through it.
"I feel passionate about sexual health checks. The NHS provides a service to check you out yet people don't do it. I don't understand why. If you ever feel there's something wrong, talk to people. It's always better to check it out. Be brave.
