Creepy guy at work...help!!!?

I would like to know how to handle a creepy coworker. He is nice, popular, semi good looking, recently married. Every time we work together he pays too many complement and it is starting to creep me out. Complement like " oh you are so hot" , what color are your eyes they are so beatiful and nail polish complement etc. I don't even say thank you anymore, just look at him with a smirk on my face.....
