Reese Witherspoon holiday shopping with her beau Jake Gyllenhaal wearing Paige Premium Denim “Roxbury” jeans in Los Angeles. Reese is currently onscreen in “Four Christmases” with Vince Vaughn although I’m really looking forward to seeing her in “Monsters vs. Aliens” in 2009 which is a 3-D animation movie about you guessed it… monsters vs. aliens.
