Jake Gyllenhaal sure is popular with the ladies!
The actor, 30, has been spending quality time with his female friends this week.
First up, Anna Kendrick got close with Gyllenhaal during a pit stop at a gas station, where the End of Watch costars stocked up on drinks and sandwiches, reportedly after a quick trip to Las Vegas with a group of friends. A source insists the two are just costars and pals.
