The `How To lose Friends & Alienate People` actor feels lucky to have had so many attractive co-stars and constantly has to tell himself he is only playing a role when he gets close to beautiful actresses.
He said: "I get to work with a lot of lovely girls. I have to keep reminding myself what a wonderful wife I have. When you have to kiss Kirsten Dunst and Megan Fox, it`s an odd profession to be in. You have to remember it`s not because they like you."
Simon also confessed to having a crush on Carrie Fisher and even queued with fans at a sci-fi convention in order to meet her.
He said "I`m hoping to meet Carrie Fisher at a `Singin` In The Rain` screening and Debbie Reynolds [Carrie`s mother] is going to be there so maybe Carrie Fisher will be there.
"I met her once at Comic-con; I lined up with a whole bunch of fans to meet her, she had no idea who I was. I had a chat and walked off grinning."
