London: `X-Factor` judge Simon Cowell has revealed that Louis Walsh is so close to the guest judge Nicole Sherzinger that it seems he is in love with her.

"He`s definitely in love. Seriously Louis hasn`t smiled like this for a long time, he``s like a lamb on a spring day, I have never seen him like this," the Mirror quoted Cowell as saying.

"He is so soft on her it is very sweet. But it`s definitely the first time anyone has known Louis with a crush like this.
