Terry Richardson & Olivier Zahm, who happen to be best friends, are my two favorite photographers. I am insanely in love with every picture they take. Olivier Zahm is the founder and owner of the french magazine "Purple", and is also known for his website http://www.purple-diary.com/.
You probably already know most of Terry Richardson's work. He is very present throughout Vogue and many other magazines, hiding behind the incredible art of photography. He last year had the privilege to shoot the Pirelli calendar. You can keep track of him on his blog: http://www.terrysdiary.com/
