"I think most of the men in Britain have a crush on her, who wouldn't?" Metro quotes him as saying.
"She has a boyfriend, though, and I'm respectful of that. Let's just say I'm window shopping - I can look but not touch."
Murs was romantically linked to his Xtra Factor co-host Caroline Flack last year before her fling with One Direction star Harry Styles was exposed.
It has been claimed that Scherzinger will spend £750,000 on flights to see Hamilton during her stint on The X Factor.
The show premieres Saturday (August 18) at 8pm on ITV1.
