Jake Gyllenhaal stopped by one of his most frequented LA spots, Urth Caffe, yesterday afternoon. Jake is spending the early days of Summer on the West Coast and was spotted hanging out with brother-in-law Peter Sarsgaard and partaking in a bicep-baring jog with End of Watch costar Michael Peña over the past couple weeks. Jake and Michael have been staying in shape for their roles as policemen in the film, which also costars Oscar nominee Anna Kendrick as Jake's wife, and Jake's bulging muscles also came in handy for another recent on-camera adventure. In July, Jake will appear on Man vs. Wild in an episode that took place in Iceland and found him and Bear Grylls scaling glaciers and volcanoes. Jake has been enjoying his guy friends and the single life since his split with Taylor Swift early this year. Jake was reportedly spotted flirting with Olivia Wilde at Chateau Marmont just a few days ago, but their reps were quick to say the actors are just friends.
