Jake Gyllenhaal Remembers Heath Ledger

Jake Gyllenhaal stops to grab a cup of coffee in Brentwood, Calif. on Sunday morning.

Earlier this weekend, Jake, 27, was spotted hiking at a Los Angeles park with girlfriend Reese Witherspoon and her two kids, Ava, 8, and Deacon, 4. It was the first sighting of the star since his Brokeback costar Heath Ledger‘s passing.

It was reported last week that Jake was in New Mexico shooting his new film, Brothers. Presumably, he flew back home recently to attend the private memorial service for Heath, which was attended by his close family and friends.

Jake is the godfather of Heath and Michelle Williams 2-year-old daughter Matilda.
