Reese Witherspoon And Jake Gyllenhaal "100% Dating"

Reese Witherspoon and Jake Gyllenhaal are most definitely a couple.

The pair worked together last year on the film Rendition; earlier this month they were spotted spending time together in New York, fuelling mounting speculation they were more than just friends, and today celebrity gossip blogger Perezhilton.com is reporting that the pair are 100% on.

"They are 100% dating," a firend revealed to the website.  "Reese and Jake are being smart about things and keeping their relationship very discrete and out of the public eye."

The Legally Blonde star has been single since her divorce from fellow actor Ryan Phillipe, who she has two children with.
