Tour de Gyllenhaal!

You can't say Jake Gyllenhaal doesn't research his roles. Gyllenhaal, who is reportedly set to play Lance Armstrong in the movie about his cyclist friend's life, was spotted yesterday in the Hollywood Hills riding his bike -- perhaps in preparation for the role.

Gyllenhaal, who has often been spotted cycling with Lance and pal Matthew McConaughey, was wearing some sort of cycling shirt unzipped -- giving all his adoring fans a nice glimpse of his chest hair. You're welcome.

Jake can next be seen in "Zodiac," in theaters in early 2007.
