The 60-year-old star said that the singer, who is currently a judge on 'The X Factor' UK, is a real hunk, reported Showbizspy.
"I definitely like Gary! He is very attractive! I think he needs an older woman," she said.
Osbourne also said that she still keeps track of what is happening on 'The X Factor' but feels the programme misses its creator Simon Cowell, who is currently judging the American version of the series.
"It is a very, very different show without Simon. I think he would like to come back. He misses the UK a lot, and let's face it, he is 'The X Factor'," she added.
