Keisha Buchanan has a crush on Simon Cowell. The Sugababes beauty - who is in a long-term relationship with boyfriend Dean Thomas - can't stop fantasizing about the music mogul when she watches him on TV talent show "The X Factor."

She said: "I fancy Simon. He is really honest with the people on 'The X Factor' too and that's good. It's his facial expressions, and I like it when he bites his bottom lip."

Keisha recently revealed she doesn't wear much make-up when she isn't working because Dean prefers the "natural look."

She said: "I'd describe my look as quite natural. I like to accentuate my eyes and keep my hair simple but occasionally experiment with longer hair extensions. I think my boyfriend prefers me natural with my hair tied back and jogging bottoms on!"

"On days off, I hardly ever wear any make-up."
